I know it's a pain in the ass to be moderated, but it's something we all went thru.  Best way to get unmoderated is to be active on your local board, so the mod knows you are not a flake.  After you establish a posting history, you might ask your local mod if he can un-moderate you.  Sometimes they have run moderation amnesty's where all you have to do is ask any mod to un-moderate you, watch for that.

I posted pretty regular for a month or more.  Mod got sick of reading my drivel & approved me.  If you don't post, have no record...  they have nothing to go on.
