How can I change my username?
If you just registered your account and you notice that you made a spelling error in your nickname, then just delete your account and register a new one. You can delete your account at MY PROFILE -> SETTINGS -> DELETE ACCOUNT.
If you're a Qeeper for some time already, then unfortunately it's not possible to change your nickname anymore. Qeep's database does not allow this kind of change yet.
We know that some users have chosen nicknames that they would like to change and we plan to offer them a possibility to change it, but the necessary database changes will take time. We're working on it.
