What I'm looking for is to compile a list of all bugs and issues as it stands... so that I have a work list.

As you asked to have a list, David, I've made three (started with one, but there were clearly three distinct themes being talked about), hopefully including everything that's come up in the thread so far. Hope that's helpful. It would be good if people could read the lists first and add to them. Please correct any of your points that I may have misunderstood or misrepresented.

Fixes to new design

Fundamental problems with old design in adapting to new challenges

Fixes to new design:

1. Fix inline moderation.
   
2. Fix user permissions DONE?
   
3. Fix switching between versions?
   
4. Drop-down menu at bottom of page to choose style
   
5. Adjust size of type for different platforms? May interfere with 'one style to rule all' concept?
   
6. New posts/today's posts?
   
7. The post actions (rep, report, quote, etc) are butted right up against the bottom border.
   
8. Add to rep opens a new tab rather than a floating box.
   
9. The first two page numbers are butting together
   
10. Some of the HTML is unnecessary and only adds to page weight, and some is invalid. You can make it a lot cleaner.
    - really? That's been obsolete for years. The name attribute is invalid on the element. If you're wanting to make something link to an in-page anchor (Back to top) then link it to an element's ID.
    And you have loads of

    ---

    elements doing nothing except putting borders on the top and bottom of the , which should just be css borders on the and

    elements with classnames like "big" when you could be applying styles based on them being inside the

    element.
    

11. Search box top right
    
12. Little symbols on the left of the threads showing how many posts they have/if you've posted in it.
    
13. Continue to provide a style that's unconspicuous at work
    
14. Provide black-on-white option
    
15. Once the new HTML is finalised you could in theory have user selectable styles by just changing the CSS.
    
16. Post and reply text is too big, not the entire design. It's the same size as the heading text which isn't great. There's no semantic element that tells you it's the post text. It's just unstyled anonymous text just sitting in a div. Semantically paragraphs should be in

    tags but I don't know if the forum software can do that.
    

17. Rep/comments function
    
18. Make front page more lively? It doesn't look like the front page of a website but a contents list in a book.
    
19. The separation of the posts is terrible; that thin black line hardly works and the line about adding reputation gets in the way.
    
20. Show new posts popping up on the front page in a thread I am following, rather than having to go to each section to check or use the new posts facility. I assume you will be adding the updates of latest posts to the right of each forum heading on the front page but if not, they are not there.
    
21. Keep option to use original style
    
22. You can currently choose whether your mobile uses the full site or the mobile version, could you do the same for styles? I'm liking the new one on my phone, but prefer to stick with the old one on the computer...
    
23. For me, the Post Quick Reply and Go Advanced buttons on the reply box seem to be faded around the text, ie it looks out of focus, but maybe this is just my dpi settings or something.
    
24. The classifieds link at the top goes to the help and testing forum.
    
25. In most forums, some of the links to threads are grey but the 1,2,3... page links are still cyan.
    
26. In forum help and testing, many thread titles/links are grey but I have never read them
    
27. The links at the bottom of the front page with all forum areas: bike polo --> classifieds; general and general go nowhere
    28. travel ----> general, ...
    
28. misc gives me a no permissions problem.
    
29. Is it deliberate that video links are centred in a post?
    
30. Clean up vBulletin's code as much as possible
    
31. Bring back multi-quote. ;)
    
32. Arial font in text editing box
    
    

Fundamental problems with vBulletin:

1. It should be possible to have a filtered view of the world: If you only give a shit about Polo, then you shouldn't see anything else. If you only give a shit about Birmingham and Polo, then you shouldn't see anything else.
   
   1. Fire up Django and write what I believe to be the right solution once and for all (open source, inviting others to make it happen). It's a real internal struggle, but I do think the new design is a major step in the right kind of direction.
      
   2. vBulletin was never really designed for multiple server setups, yet you need a multi-server setup to run a site this big.
      
2. Oh, and if I had my way, I'd obliterate that WYSIWYG editor and replace it with a markdown textarea and inline file uploading of attachments. The posting interface of vBulletin is horrific. Just so distracting from just getting content on the screen... and uploads are just broken, the whole way they're done... just so broken.
   
   

Fundamental problems with old design in adapting to new challenges:

a. Diversification of access device (android, iphone, kindle, tablet)... the old design simply does not work well on those things. The devices I can support by changing HTML and CSS as the new style proves.
b. Growth of the community, gravity of LFGSS as a cycling forum, noise levels and junk. This problem is different from the device problem. Whilst we all cycle, your specific interests might be different from mine, and certainly amongst some people they really don't want to see or deal with the noise levels associated with the whole forum (when you do a search, you want it to be only amongst the stuff you're interested in and nothing else).
Reddit has things like subreddits and you can divide up the whole of reddit to just the shit that tickles or interests you. It's not really possible to fully block the noise on a hierarchical forum system, which is what vBulletin is (and the same for PHPBB, Vanilla, XenForo, etc).
