What are the valid characters and valid lengths for webnames?
.au names can contain the English-language letters A through Z, and the digits 0 through 9. You can also use hyphens, but hyphens cannot begin or end your webname and you cannot have two hyphens in a row. Spaces and special characters (such as !, $, &, , and so on) are never permitted. The minimum length is 2 characters and the maximum length is 63 characters (excluding the “http://www” portion).
