Anybody who thinks we need another forum needs his head examined. There is no shortage of Wine forums. We just need to use the ones that already exist. Adding a new one will just fragment the community further.
In particular, there are two forums right now that people already use to discuss wine problems: a generic one at http://www.linuxforums.org/forum/wine/ and an Ubuntu-specific one at http://ubuntuforums.org/forumdisplay.php?f=313 Let's just link to them. I'll submit a patch to do that in a minute.
And I like Griswold's idea (on IRC) of improving the current appdb in small ways, e.g. changing the reply behavior to not open up a new page.
For goodness' sake, don't create yet another new forum! - Dan
