Is there are way to edit your name on Fluther?

No. Just send a private message to ben or andrew and tell them why you want it changed. They might help you on that. Other than that, there is no way to change it.

Eidt: Your account seems pretty new. Why don’t you make a new account?

Not that I know of. Maybe try what @BonusQuestion said, but I doubt it. It seems like you haven’t been here long, why not try and sign up with a new name?

[Mod says] There is no way to change your user name on your own. If you have a compelling reason for changing it you can ask that it be changed, but there is no guarantee that your request will be granted. Your best bet is to create a new account.

Seems like ben/andrew changed it for you. Congrats!
