How to get UPPERCASE usernames in GS and Multi User module?

[JWH_Matthew]

The reason the username is lowercase is because it is also the name of the file. PHP requires that you use exact capetilization so we decided to force lowercase usernames when adding users. At the time this was the simplest option.

However I will check but we may be able to change the code a little on the header to fix this.

Sorry for the slow response.
