The suggestion has merit. But let's face it, if 'they' don't use the search function before asking the question it's unlikely a FAQ sub-forum is going to improve the issue of repetitive questions.
However, there is potential benefit for the instructiors, admin and old, cranky members... instead of retyping the same ol' answers to the same 'ol questions one could simply and quickly refer the inquisitive newbie to the FAQ section. That in itself may make a FAQ sub-forum worthwhile.
Some of the work is already done, just click on the Help tab and what's revealed addresses many of those newbie questions. But the Help tab is available almost everywhere -- [u]except[/u] on the forum pages...
