Thefiringline.com and pistolsmith.com are two in which I'm a member and use the same public name - kogatana. The first one is quite prolific and moves quite fast. The second boasts members that are actual professional, working pistolsmiths, some of whom are known nationally. It's a little slower but equally informative as the first. I thought about asking the owner of this BB if we can start a firearms forum and volunteering myself as moderator but my schedule is so full that I wouldn't have the time. There are so many others that have a section devoted to firerams and RKBA issues that it is becoming difficult to keep track of them. Many members of one board are also members of others, frequently using different names. Hope this helps.
