although many problems might not be directly related to ls (core), it still makes a lot of sense to include these problems into an faq, or better a wiki.

best example i have in mind right now is the workaround for vtray/systray magic pink borders. simply set iconsaturation to 254. you wouldn't normally think of that, and if i didn't know about having read of a workaround some time ago in these forums, i would rather ignore the pink borders and accept them and wait for an module update fixing it.
a wiki could contain all these tiny or huge-scripted solutions, and people could easily update them if neccessary. it would prevent people from always asking the same questions, it would be easy to keep most of everything up to date (which is more difficult in a forum, because there're quite a few threads on some topics), and ... erm ... oh, i'm finished. :)
