I love this bit from the site:
We are (terrified) happy to announce the live appearance of four representatives of The Klingon Empire: the Duras Sisters and Gowron and Martok! The Klingons, after an extended period of talks (and as yet unexplained disappearances of human negotiators), have agreed to appear at this convention provided they are treated with honor and dignity.
