That they do... That they do...

Rather than developing a completely new system for marking those who were GMs before, why not adapt an existing one? Should be far easier to do that.

That's what I was suggesting by adding a new section at the top of the page- <Created By- Name>.
Perhaps that could also utilize a banner, but how complicated would it be for the system to understand when the original poster is no longer marked as "GM" , and should be reclassified?
