My username isn't what I picked

[4rbs]

I've tried a bunch of times making an account with my email and everytime I choose a name it doesn't allow me to have the name I pick when I make the account even though the username is available. It just proceeds to give me some random username with a bunch of random numbers and letters. Anyone know why that is?

nevermind posting this allowed me to pick a username..

update: I still can't log in with the username I chose
