Am i stupid?

[Psychdrone]

I hope this is not too simple,
HOw do i put a bar, above the users naem, like allrpg.com?
and how would i make it only appliable to a certain group, liek admins or mods ext.

second question, How do i make a field to show up on the postbit, but only i can edit it for each member,- Liek a new profile question, but only i can fill it in, and how do i make it show up on the page, i know it has to do somethign with the post bit,


Thanks! a bunch
