Our username policy says how you should choose your username. Put simply, you should not have a username that people find offensive, advertises a real world group or company, or is confusing (for instance, if it pretends to be another user).
If you have already made changes and wish to keep your changes under a new name you may ask us to rename your account. If you want to, please follow these directions:
If you have made few or no changes, then it would be a lot easier to simply create a new account.
Please note that the software Wikipedia uses may automatically block you from creating a new account – this is a mistake, and shouldn't have happened. If this has happened, attract attention using the unblock template as explained above, and an admin will fix it for you.
If you think you shouldn't have been blocked, add ((unblock|your reason here)) below or email the administrator who blocked you. You can also send an e-mail to simple-admins-l@lists.wikimedia.org and an administrator will look at your reason and reply.
