It must be noted that when Mr. Gerrold is not writing questionable science fiction, he makes a large part of his living selling things on Ebay, (user ID davgerrold@compuserve.com). This author must be in dire financial need. Because he has sold several copies of the current manuscript to the upcoming Chtorr novel, (A METHOD FOR MADNESS!), on Ebay. He has also sold such notable things as original Tribbles, (props from his Star Trek episode).
Finally his Chtorr mythos has been turned into a roleplaying game with GURPS War Against the Chtorr, which is currently out of print, (but is a great read).
He also has another website at www.chtorr.com
