smallstreams.com. It's a very interesting site with all the ingredients I love - tiny water, beautiful trout pics, and of course gear talk. The site is also moderated closely and has a zero tolerance policy on poor behavior, which is a huge plus. The unfortunate side-effect of this site - I'm itching for a bamboo fly rod now - shhhh...just don't tell my better half!
So after this, I've taken inventory and noticed that I'm a member of (and participate in various levels) a handful of fishing forums. My standards are PAanglers.com & WhereIFish.com, but I also drop in on EPFR.net and the Tenkara USA forum regularly. Now add smallstreams.com to the list and yes, I may need to go cold turkey.
So do me a favor and give me my next fix - go to the comments section and let me know if you belong to any good fishing forums and why you like them.
