I do not see any advantage at all in sub-forums - only confusion.
Special cases require special treatment
Surely we can very easily distinguish whether:
"the post is an annocuncement" (so it belongs to announcements)
"feature request/ wishlist" ...
"bug report" ...
IMHO at least these four categories are very easy distinguishable even for a small child.
Please look at the traffic at the original Bibblelabs forum.
The categories there has a great importance.
And it has served for majority of users very well.
Thanks to that approach, too, the Bibblelabs forum was so good place.
I do not want to mix plugins related stuff with failures to start on linux for instance.
even "linux related bugs" ... is for me very easily distinguishable. When ASP refuses to start in linux, it is surely not an announcement, not a feature request, but a bug, and surely LINUX related, not windows.
From my POV, when I am trying at least a bit, I can logically place my post. Of course, when there are more then four basic categories, often there are more possibilities to classify a post. But what is perfect in our world? Is the unability to gain perfection an excuse for the total lost of trying to make something better?
Why do we use folders on our harddrives?
We have search engines, so why folders?
Yet we use folders.
(sorry for slightly passionate post, but I do feel it so. I am scared of possible chaos on the forum...)
