Confirmation before username change
When you go to change your username, there is no confirmation to make sure the change was intentional. It should ask for a confirmation if you are making a 2-6 month commitment. It should just ask "You are about to change your username, is this correct?" As it is now, you can be trying out different things and if you accidentally hit enter, then you have to live without a username of your choosing for 2-6 months. I am really shocked this hasn't been implemented. I can't even look at a website without confirming my choices about cookies, but I can commit to a 6 months name change I didn't want. This is not right.

I've accidentally changed my username. And I didn't even click on "Save Changes". And normally say you changed your password, e-mail, etc. for that account. You would have an e-mail sent for authorization to make sure it was you. So if you accidentally or someone changed your Twitch username. Instead of waiting 6 months to re-claim your Twitch username. You would get an email to authorize that change to the username.
