The "rules" for what is or isn't a TLD have changed over time. I did see a nice article the other day in the RFCs about some pragmatic ways to do this "right" without killing yourself, or coding something that's bound to break within a very short time. Don't know the RFC# offhand though, but I got the feeling that it was pretty recent... The LAST thing you want to do is hard-code the list of known TLDs from today, because that will change too often. .co.uk is a TLD, afaik... -- Some people have a "gift" link here. Know what I want?
