Now that I had a bit more time to think about it, I think that there shouldn't be any radical changes. Sure, that the Information topology, like the categories and topics, could be reshuffled and improved, but in the whole, I think the forum is ok because this is a community, and though a virtual one, its strenght isn't shown by its strong points or weak points, but by the overall experience that it allows to give to its visitors.
Discussing about creating even more sub-foruns is conter-productive. That will only lead to more confusion and one day, without you know it, you'll need a manual (or a tour guide) just to know in which forum a person should post. Not to mention that it borders on Eugenics. "Lets get rid of dumb people and put them in special places. Where does it begins? Where does it stop?"
Good or bad topics, they all contribute to the Jref Foruns experience, and as long as the excesses of guide lines are curbed, it will be fine.
