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

[mrmut]

Is there a way to make usernames UPPERCASE?

I did achieve this in top right corner with:

Code:

.wrapper #pill li.rightnav b
{
text-transform:uppercase;
}

However, I am not particularly happy with it.
Is there a way to alter this? - Or maybe have "First Last" username?


Thanks!
