The Joomla! Forum™

I actually thought about your concern and yes, it is a roadblock. I'm not entirely sure how those two sites (or other sites) enforce such a policy, but I can definitely see that something like this can be done programmatically...would need to mod SMF though. Anyway, whatever the forum admins and mod...

I have a suggestion for the site showcase. One thing I've noticed in the showcase forum is that a lot of people put their sites up and say "look at me! look at me!", but they don't want to review other people's sites. So essentially, it looks like only a handful of regulars review most peoples' site...
