Bringing back this wiki idea.
I like wikis, especially for community driven websites seeking to spread information like mtbs3d.
Forums are great for discussion, recent topics are immediately visible, but if you're looking for some generic information you almost always have to serach for your topic for a while, and then read the whole discussion to find what you're looking for.
Wikis are much easier to navigate if you're looking for information rather than discussion (i have never understood how wikipedia news and discussions worked)
Information and guides are immediately available in the front page and since everyone can modify it, if for some reason the original author of a guide or article leaves the community it doesn't matter, anyone can continue working on it, and content is shown in topic based trees and/or listed alphabetically rather than last updated.
Now about how to make it work, i have never deployed a wiki but i know they are just giant common databases and organisation is only required for the actual displaying of information. So basically you could put almost everything on mtbs on the wiki : news, image gallery, articles, game compatibility infos, etc...
As far as presentation goes, we could have one part with all the different guides (a very beginner friendly part)
with : what is S-3D, what hardware do I need (the hardware guide), what software do i need (some s3d diver guide), how to setup my games properly (separation, convergence, pop-in vs pop-out, basically make a more user friendly gaming equivalent to the Autodesk cinema S3D guide), etc...
The second part would be the big list of games
for each game, I'm thinking about having something like the wine application database, where for each driver, users share their experiences, and tweaks :
http://appdb.winehq.org/
You'd have some sort of S-3D summary of how the game looks like in S-3D, on the summary page, you'd have a quick description of the game, the MTBS certification status, an overall mark per driver (how much of the game works in S-3D) and a link to a per 3D driver dedicated page (native, nvidia old, nvidia new, iz3d, tridef, and others...)
