Andy, If you subscribe to this e-zine, you`ll get all the leads to the forums you want. Dien Rice scours the various business forums and lists the most interesting posts on many of them. The real estate ones are usually in the last several listings. This is one of the few e-zines I have subscribed to for more than a few months! I find Diens` work a most valuable resource... it saves me a ton of time... and has done so for years.
So far as the stock market forums, I`m lost there... I don`t know of any that have any measure of credibility. The ones I`ve looked at are all aimed at selling you something, and that`s always the flavor of the day. Sorry.
