This is just a tiny extension that allows you to disable the editing of screen names within the control panel on a per-member group basis. The only reason I wrote it was to help out in the forums. I have no real use for it but maybe you will. If you have any questions about it just drop me a line. For now there are no plans for it to be ported over to 2.0 (due to the huge changes in hook availability).
If a member tries to edit their screen name on the My Account CP page and they are in one of the denied member groups, they will see the following message: “The administrators do not allow screen name changes.”
Looks like no one has left any words of wisdom yet...
