Well you should hang around the forums for awhile get to know everyone... and get everyone to know you.. as in post in the diff forums and generally chat with people. After you have done that, if there is a forum that is your specialty, you should pursue talking with the other moderators... from what I have seen from you, you seem to be a Diablo 2 fan. So im guessing that would be the forum best suited for you to moderate. We already have a great mod for D2, "User Name #1" but that doesnt limit your chances there are still some forums open. Basically it comes down to getting yourself known, having experience with the theme of that particular forum that you want to mod, and talking to the other moderators.
