Thread:Project:Support desk/Username as emailadress/reply (2)

Hi Daniel,

the "@" sign is not allowed in user names, because MediaWiki uses it internally for interwiki users, meaning for users, who have their account in another wiki. If you do not have multiple wikis, you can try to change this behaviour: To allow the "@" sign in usernames, you should set

in LocalSettings.php.

To change the case of the first letter of the username, you would have to change the case of the first letter of the user's page. I think there also was a $wg... variable, whose name I currently do not recall, which allowed to do that. However, afterwards basically all pages can start with an uppercase or a lowercase letter. I don't know, if you want that; maybe living with an uppercase letter for the emailaddress is the better choice...

Would be interesting to know, if giving user rights to these users via Special:UserRights works after you have set $wgInvalidUsernameCharacters.
