I might stop doing name changes. It's easy to mess up!
Brian was shobute and is now shobute again. Briachek's name is Brian but his username is briachek.
I changed shobute's name to Brian, then he asked to have the old name back. I supposedly did this (although I think I actually did something else which thankfully did not work) and then emailed briachek to tell him his name had been changed back to... briachek.
Sorry guys!
