Does it really say "Username : Unregistered"?

I don't have Calender active on my forum but it looks like a mod associated with calender events. I don't think unregistered users should be able to do anything with calender events.

Yeah, it says unregistered. I have several mods on my calendar... maybe the mod linking theads and calender events.. I'll check.

Thanks
