Who here is a Vet?

[Trumanator]

Really, unless we want to go through some system like Calahan is proposing, the only real way to figure out who the "vets" are is just to spend time on the forums. Even then, its a pretty ambigous designation.

Eh, well, vet = veteran I guess, so the only real qualifier is has been around for some time/played a lot of Dom3 games. I don't really see why you should need a list of it nor why you should need any explanation.
Unless you are thinking of making a list of skilled players, but that's practically impossible short of personal opinion considering how unbalanced/different games can be, unless you are only counting the top 5 HoF.
