What are the valid characters for a domain name and how long can it be?
The only valid characters for a domain name are letters, numbers and a hyphen "-". Other special characters like the underscore "_" or an exclamation mark "!" are NOT permitted. A domain name cannot end with a "-".
Example: yourcompany name.com (incorrect, No spaces allowed)
Example: yourcompany-name.com (correct)
A domain name can be up to 32 characters long (minimum of 1 character) -- not including the characters used to identify the Top Level Domain (.AG, .NET.AG, .COM.AG, or .ORG.AG).
Can my domain name be revoked or my registration process terminated in any way?
Yes. A domain name may be revoked if it is used for offensive, immoral or illegal purposes, including "Spam." A domain name may also be revoked if found to be in contravention of published policies and procedures.
