Just one point that was originally raised by Joe Offer. With internal links, it is better to leave the http://www.mudcat.org part out of the link.The reason for this is that the full URL will be built up according to the address that is being used by the user. As an example, shorty could be down and www not working so the user is on loki, giving the full URL would fail but using the relative path, the full URL would become http://loki.mudcat.org... and would work.
