All moderators have a one worded name. Like Estel, Strop, Carlie, Flipski etc. No one is named "Superman3434" or "jjsdk 34" Or anything like that. I thought it was weird...
Haha, it isn't a requirement, I assure you. It is merely coincidence. Perhaps it is just that the more mature members tend to have more mature names? I really don't know. But we do not try to pick people with one named screen names, we pick the person behind the name, whatever it may be.
