We have a lot of gun ethusiasts. Some of them are dealers, some collectors, some smiths, some armorers, some neophytes, some hunters, some LEOs, some long range rifle shooters, some into skeet or trap, some active duty military, some not old enough to vote yet, some serious pistol competitors, some MILSURP shooters, some that like Glocks/ S&W/ Colt/ Taurus/ SIG/ Winchester/ Browning/ Ruger, etc.
Don't know that we have ever counted the herd, everyone contributes what they can, and the folks that do this for a living are especially regarded for their insights.
Additional categories would be up to the Admin- folks that the site belongs to. Those of us that are Mods just try to keep the wheels from falling off the thing.
