Not as far as I know. Although it’s HIGHLY not recommended, you could edit the name in the database (totally 100% at your own risk). It might be easier to create a new account and make him key master too and perhaps running a MySQL query to associate all old posts to the new account …
In short, there’s no graceful way to do it that I know of.
In bb-includes/capabilities.php I changed line 27 (I am using 1.0 Alpha) to the following:
#26 return array( 'keymaster' => array(
#27 'name' => __('Admin'),
You could change “Admin” there to Scott or Chris.
I have been doing this since .75 with no ill effect. I hated the “Keymaster” name under admin.
To get rid of the Keymaster thing the easiest thing to do is set a custom member title for yourself. That’s what I did. ^^
That is the easiest way for sure fel64!
