Marketing Microcosm

To what extent can I customise my forum in this beta phase ? (http://porridge.microcosm.app/microcosms/173/) like can I replace 'microc.sm' logo top right with my own logo/pic?

Yes, go to https://microcosm.app/ to sign-in (top right) and then edit your site.

On the edit page you can upload a new logo, change the title or description, edit the background colour, change the font colour.

And eventually we'll add the default permissions management and navigation management to that page.

Also does the 173 mean this is the 173rd microcosm?

Yes.

Also is it worth grabbing some key microcosm domain names now which may be worth loads in the future (Like flyfishing.micrco.sm)

Not really.

As you can see with Islington CC, most people will use their own domain names with the service.

So there is no point trying to have a landrush on subdomains.

forum.flyfishing.com could easily point to jhasgdfjkhg.microcosm.app and it would be invisible to the world.
