What would you do if the forum had a subscription fee (to post classifieds, etc)?

Your position is different to your examples because the fee you would take come from the contributers, not from buisness advertising or a service charged. Wikipedia staff may take money, but they don't get it from the average user. Same with facebook or other social networking sites, staff make money, but not from the members.

Like I mentioned before thats my more ideological stance. In reality I'm not that bothered if you do, but in principle I don't think you should. And it seems I'm not alone on this. There seems to be a real sentiment of not making a profit. The members seem willing to pay, and suggest you shouldn't have to, but I don't think we should pay, for you to make money, when we all provide the content.

Who cares if he makes a bit of profit on top, I mean seriously Harry, do you have any idea the amount of work that goes into maintaining or building something such as this site? I'm sorry, I know this comment is not aimed at me, but I find that paragraph borderline offensive considering the financial and time sacrifices made by David, I mean the fact that you think we shouldn't have to pay because we provide content.....no forum no content its as simple as, and David created this forum, so maybe you should be a bit more grateful, happy even, if he gets a little something back in return for all his hard work.
