A mod is a moderator who watches over the forum and when ever some one breaks the rules he/she will delete the thread/post where the user broke the rules. They also ban members when they break the rules. There is only really 1 agent around here and thats thuggy. He is like a recruiter or something
as for becoming one you have to establish yourself as a member make many good posts and show your consistency as a member. Also timimg is a factor because WA doesnt always need mods at a certain time.
