just a little suggestion...
there seem to be a large number of posts beginning with.. "where can i find (insert part here)". is it possible to set up a parts resource page where members can add sources and give a general description of what they carry? (or is it already on the site somewhere and i just missed it?) i know nothing about what it takes to run a web site, so if this is more work than it sounds like, i'll believe you. just thought i'd ask.

Well, there is the classifieds. It is free, so anyone who has parts or a parts cart that they are willing to share can post. There will soon be a new classifieds with a seller rating program like ebay. This may help users have confidence purchasing.
