Editing Eurovision Wiki:Changing username (section)

=== Limitations and restrictions ===
There are technical limitations and restrictions to the username change process.
* Accounts cannot be merged or deleted. They can only be renamed.
* [[Wikipedia:Temporary accounts|Temporary accounts]] cannot be renamed.
* Edits made while logged out—identified with an [[Wikipedia:User access levels#Unregistered (IP or not logged in) users|IP address]] or temporary account—cannot be re-assigned to a different username or merged with another account.
* Usernames are subject to [[Wikipedia:Naming conventions (technical restrictions)#Restrictions_on_usernames|technical restrictions]]. Specifically, they cannot:
** contain the <code># < > [ ] | { } / @ : =</code> characters.
** start with <code>~2</code>, as this is reserved for [[Wikipedia:Temporary accounts|temporary accounts]].
** contain various control characters, unusual whitespace, or [[Private Use Areas|Private Use Area]] characters: U+0080–U+009F, U+00A0, U+2000–U+200F, U+2028–U+202F, U+3000, or U+E000–U+F8FF.
** be an IP address or resemble an IP address (for example, "564.348.992.800" is not a valid IP address, but since it looks like one, it is an invalid username).
** be on the list of [[Wikipedia:Reserved usernames|reserved usernames]] (e.g. [[User:MediaWiki default|MediaWiki default]]).
** be more than 85 bytes long.
* Usernames should contain at least one letter, and may not consist of only numbers and punctuation.
* Usernames may not contain characters from unusual scripts, or contain characters from multiple non-Latin scripts. [[Wikipedia:AntiSpoof|Learn more about these restrictions]].
* Usernames may not look too similar to existing usernames. You will be notified if the username you requested is too similar to an existing one.
* Usernames cannot begin with a lowercase letter. The first letter of a username is always capitalized.
* Underscores and spaces are considered identical by the MediaWiki software, so ''Jimbo Wales'' and ''Jimbo_Wales'' are considered to be the same username.
* {{anchor|transparent}}Renames are recorded publicly in the [[Special:Log/renameuser|user rename log]] and [[m:Special:log/gblrename|global rename log]]. This is done in the interest of transparency.
