I wish we could change our names. I had an account here that was honorable also but i just hated the username so yesterday i went through the long process to get a new account. In case you are wondering how to do this, here is how:
1. Make a new windows live id
2. if you want to use this for xbox live also, you need to link your gamertag to the new account. go to account settings on your xbox and choose change windows live id.
3. create a new bungie.net account with the new windows live id.
Presto! You will lose your title but if you dislike your username as much as i did mine, this might just be worth it. Also, if you have any microsoft points they will transfer to the new account too.
