I was one of those who started back in the bulletin board thread days back in the mid 90's and was involved in many forums in the past years. I am big into cars (mustangs), 4x4's and bikes (street and dirt) and used to interact heavily on some of the big name mustang boards and other motorsports forums. I have been on LE and firearm related boards for a long long time also. I have helped to develop, moderated, been staff, etc, but when you get married, have kids and career develops you find less time and I gave up the moderating and Staff stuff altogether and I don' really visit forums with any frequency anymore. I visit this forum about as much as I frequent any forum now.
Screen names have all included my current user name. For firearms related I have been around the following, but not all at the same time;
glocktalk (no longer visit)
The Highroad (no longer visit)
Officer.com (no longer visit)
Sigforums (no longer visit)
lightfighter.net (rare visit)
ar15.com (long time member, occasional visit)
socnet (long time member, vetted AP member, occasional visit)
m4carbine.net (long time member, vetted Industry Professional member, less frequent as before)
pistol-training.com (vetted Subject Matter Expert member, occasional visit)
So 2ahawaii is about as frequent as I visit any site and I visit about 3 on occasion right now.
