A forum is a place to congregate (virtually, in this case) and flap our respective jowels about whatever happens to tickle our fancy at the moment. It"s a collection of streams of (un?)consciousness with no organization beyond iffy titles that are soon ignored as discussions veer off to wherever. Finding anything specific is impossible, especially when the current software returns an entire thread that can be scores of pages long. Yes, there"s Google, but, you still get thousands of posts returned in no particular order if you didn"t happen to guess precisely the right search terms.
The wiki is the organized repository for long-term information that can be updated while maintaining the correct order. Yeah, it requires more effort than posting and means putting a bit of thought into it and all that, but, the small effort required is more than compensated for by the thousands of hours saved by others actually finding what they need in a logical order. The ability to format text around images in the wiki is also far superior to the one-dimensional flow of a thread, and auto-generation of tables of contents is a clear bonus. Please update the wiki with anything even just one other person will need, rather than just allowing it to sink into the forum abyss, never to be seen again.
