Self-reduction of privilege.

[ProgrammerDan]

From report:

I made the group GRP. I set one other owner, which is Redacted. Redacted set it up to where anyone can join by entering the command "/nljg GRP hi". Earlier yesterday, I was trying to tell someone to say "/nljg GRP hi", but I had accidentally entered the command myself. Instead of telling me I was already in the group, it said I had joined as a member. All of my owner perms were gone. I asked Redacted to re-add me as owner, but he told me it listed me as Original Owner, so he was unable to change my permissions.
