I have been saying for years that I would like to see a 'Link to common threads - look here first' thread at the top, as other forums have, but understand that 99% of the time new members come here and hang out for months, asking questions without ever looking at the few pinned threads at the top of the page.
We don't mind answering questions, but if I had a dollar for every time I have told someone to check out Ekie's guides at the top of the page, well, I could buy that boat I've always wanted.
Retroblackrifle.com is another great resource that people seem to rarely use. It use to have a retro buy and sell forum (something that has been mentioned here dozens of times) but it didn't get enough traffic, so Tex shut it down rather than have to monitor it. There is a shit ton of info in the archives as well if people took the time to look.
