All mods have the ability to add a moderator title under there name, i personally chose to not do it. I don't want people to listen to me because i am a moderator, i don't want them take my advise or behave differently just because i am posting in a thread etc... That is why i have never had any different title under my name, i can only guess the other mods do the same, we tend to operate more in the shadows deleting spam before users can see it, approving threads and posts of new users, and finding ways to make the forum a better place.
But to answer your question as of now vtec6000 and ijwhiteman, there will be a few more coming soon. But don't look at us as moderators in the traditional sense, we are more "helpers". I never want to see this place become a forum where mods only purpose is to stop e-fights and enforce rules. I'm sure most people have noticed this forum has no written rules, it never has. Just the unwritten comon sense rules to respect eachother and it has all worked out well so far, as the forum grows this may change, but i hope we can keep it this way
