Change a username

Arduradunorokorrakgks ha preguntado...
How i can change my username? I go to account.riseup.net and click in "change username", and all new username names said were "not valid". Why happens this?

It may be because of the format of the new username you are tying to setup.
It is not stated there but this is the format that is accepted by the authentication system: Usernames may contain lowercase letters, numbers, hypens, and underscores. Usernames must start with a letter or number.
Please, try with an username that complain with that format and you should be OK.
Let me know if that doesn't work.
Take care.
