Is there a way to change your user name that displays below your avatar? (sinisforgiven on mine)
Or is this permanent unless you create a new account?

Sorry to add to an old thread, but since this is a top hit when googling this issue and the thread left it unresolved, I thought I'd answer the question.
You can easily log in on theknot.com -- using your thebump.com info -- and under "My Account" there is an option right there to change your username. Not sure why "My Account" on thebump doesn't have the same option, but since all the sites are linked, you can just change your usename on theknot and it will automatically update on thebump (and thenest, etc.).
I hope that's helpful!
