Editing username.

So I installed WordPress 2.0 and automatically it creates the admin account with a username of “admin”. I then integrated MiniBB into WP and noticed that all my posts were going to be by the author of “admin”. I was wondering if there was anyway to changed “admin” to say… AFireInside. ^_^ Obviously I could just create another account (AFireInside), give it admin rights, and be set. I’m just a tad bit OCD and would like one admin account.
