Yep, ask plenty of questions. You can tell how knowledgeable the responder is by the number of builds in their forum lower banner/signature line. Don't listen to anything I say because not only do I not have a lower banner, I don't even know what the proper name is for the lower banner!

Seriously though, you will work out pretty quickly who the regular contributors are and what they are good at. Simon B (above) is very knowledgeable, more than his 4 builds would suggest. Phrozin is the guru on paint. They will also point you to previous discussions.

What are some of the gaps you mention in your post?
