One quick thing...

Looks like you don't have a username set up, let's get that all squared away!

YESSSSSS, {{user.username | lowercase}} can be all you!

Sorry, somebody nabbed {{user.username | lowercase}} already :(

Yikes, a username is required!

Ooops, this one is too short (2).

Just a bit too long is too long (14).
