3 and 4 letter domains

Short domain names in major top-level domain zones (COM, NET and ORG) are extremely popular. At this moment there are no 3 or 4 letter domain names available for registration in these zones. Web-site owners might use this kind on domain names as acronyms or just easy-to-remember words.
