Domain names can contain A-Z, 0-9 and the
'-' (hyphen) character, character case is not important.
If the domain name you want consists of multiple words, try separating them with a hyphen if it is not available.
Names cannot start or end with a hyphen, and cannot have two adjacent hyphens.
The best names are short and descriptive, but longer names can
be useful too. Don't register trademarked names (unless you are the trademark holder!) as in most cases the registration authority can take the
name away if a dispute by the trademark holder is upheld.
