This forum was literally the first thing I discovered on the Interweb when I got access back in 08-09 and Googled B-460. Took me a long time to figure things out and I'm sure I annoyed more than a few members.
The web is a good research tool, but I'm finding it's shortening my attention span for digging deep when asking a knowledgeable person/group a question can get you quick results.
A couple forums I'm using have an introduction requirement. I assume this is what Lee is referring to. Your first post has to explain your interest in what the forum is about, and can't be items for sale.
I don't have a problem with people looking for values here (though I generally don't have the knowledge), and I think there's been a few occasions where established members have purchased items put up for valuation. If items posted here have value to a member, all the better.
