what ever you do, dont ever NCC.
1. it takes ages
2. it messes up inviting and stuff
3. a unioner is damn easy to set up. tripple bribe and you are good to go.
4. go with a "special" letter like brackets etc in front of the tag, so friends and foes can easily see you on the top of the list and don't have to scroll all the way down. thats my problem with the VF) tag. it sucks.
