What are the username guidelines?

Your username must be between five and 25 characters, and can include any of the following:

1. Letters (a, b, c, etc.).
2. Numbers (1, 2, 3, etc.).
3. The following special characters: _ - @ . (underscore, hyphen, "at" sign, period).

You MAY NOT use curse words in your username. You MAY use your e-mail address if you like, but this will expose your e-mail address to the ThirdAge community. Usernames are not case senstive.
