The mods have no say in this, I think only steet could change it.

I'm not sure. My only guess is that it's confusing to people to have a name change to a character, even a small one. Say you have a char named Shirley, and then a month later change it to Rebecca, people are just going to be confused trying to search for your char if they didn't get the memo. Other than that, I don't see any other reason why we can't change our character names.

No you can't. Even if I wrote to mods that I made mistake in my char's name and I would like to change it they didn't reply...
