Yeah +1 from me too. Cream Tea has been extremely helpful answering my questions but others could learn from his responses too!
 
I'm not opposed to the idea but I can't see it being very popular and used much.

This is one of the things that could actually bring in new members in my opinion when threads start getting indexed by Google. When I'm searching for mapping tutorials or help I end up on all sorts of forums I never knew existed, some of which I've signed up on to ask further questions.
 
Good idea, although I think it could be expanded to a proper mapping and modelling subforum, not just limited to requests as that could be done in just a sticky.
