and I found a site other than BSW which offers it...www.gravon.de
I can't vouch for it yet, because I've not visited during a Tichu game in progress. However, it let me launch the java window and enter a username sans password, and enter the game applet. I sat at an empty Tichu table just to get a feel for it, and it just seems a lot more user-friendly and comfortable than BSW.
Tichu is one of those games that I've read up on to death but haven't played yet, but am eager to. I wonder what the Tichu traffic is like there when it isn't 1 AM in the Eastern U.S. and 7 AM in Germany...
