[xwiki-users] Suggestion - case sensitivity in user names (login id)

I have seen confusion for users caused by the case-sensitive concatenation used for the default login id, i.e. FirstNameLastName - especially for French & Italian names. I would like to suggest that additional instructions be presented at the time of registration indicating that login ids are case sensitive - and/or perhaps have the option of using lowercase only for the default loginid, or remove the case sensitivity for login ids.
