ET is of course good... What other forums are active? I came across "BigMikeTrading"... What others would you recommend? Thanks!
wilmott and linked in both deal with traditional technical analysis techniques as well as more modern mathmatical approaches. there is also trade2win and traderslaboratory, but they generally see less activity than big mike
traderslaboratory.com is good. And for some reason people only talk about trading instead of bagging each other.
The tradingblox forums. High signal to noise ratio on that one. (You don't have to buy the software to participate.)
