Short, concise description of the idea
Users creating accounts should have to confirm their usernames before continuing with the account creation process.
Full description of the idea
There have been a bunch of support requests recently made by users who are irked because they've created an account with a typo in the username. I think that implementing an extra step could cut down on username typos. This could be in the form of a "re-type your username here" sort of form (like that used for password confirmations) or it could be a separate page or a Java thing. A lot of users seem to mistype their names and then are annoyed when they have to wait a week or pay $15 to fix their mistakes.
