Can you actually see the function for username change? If you can it should work, maybe it just takes ages to change it for old accounts. There is a profile I can copy if you don't have the function.
Try now....don't laugh but found another button, I'm not sure if that's a good thing or not. Whoever created these control panels wants fooking shooting in the bolloxs.
I’ve got loads of new icons in the text reply box bit, **** knows what they’re all for but the username still doesn’t appear when I go into edit on a users profile.
