I realised tonight that I as admin can change password for a user, but not the username. Which causes the unfortunate situation that someone that may change blogs/sites often (it happens quite often in my list-world) or add more than one at a time - when their old ones are removed they are stuck with usernames like: "Normalusername-1234346-345675". I noticed that I as an admin can change the name of the account owner, but the username. So I can not reset username to its original :-( One solution would ofc be to tell user to change url etc at control panel. But I feel it to be extra work when it have to be easier for admin to be able to change it no?
