The Marathon wiki

The wiki software allows bureaucrats to change any user account to a new name, as long as it's not already in-use by someone else.

All edits made by the user will be changed in the edit history to reflect the change. However, there are some limits:

Each user may only change their name twice within one year. Changing & then reversing the change counts as two renames. So e.g. going from Alpha to Beta and back to Alpha wastes your rename privileges for the year. Therefore please be 100% sure you'll be happy with your name change! All requests go at the bottom section of this page, not on the user talk of bureaucrats.

Instructions

1. Create a new subsection at the bottom of the page using this syntax: === CurrentName to NewName ===
2. Below this, use {{rename user}} and put both your current and desired names (both case-sensitive), using this format: {{rename user|CurrentName|NewName}}
3. Leave a comment as to why you want the change after the template and then save the page.
4. Bureaucrats will check this page regularly and if accepted can use the "Rename" link on the top-right corner of each section to directly change the username and move all userspace pages.
5. The bureaucrat will say whether the name change is accepted or rejected in each section, and if rejected, why (such as already done twice this year).
