Just thought I would give this thread a bump because I'd been thinking of it lately.
The more stuff gets posted in the Showcase forum, the more disillusioned I get ... perhaps its a consequence of the software being free but it seems almost none of the projects using MyBB are serious or developed. This, in turn, is going to give the negative impression of MyBB as being used only by newbie, unsuccessful sites. I know if I was a new user browsing through the Showcase forum, that would be the impression I would get.
MyBB should be doing what it can to draw attention to the fact that it's capable of great things and that great sites can be built using MyBB. Not only that, it would help strengthen the bond between MyBB the product, and its users.
