MAHC Advanced HTML Chat
(Please note:This demo sometimes gives errors during login, either reloading those frames or re-logging in seems to fix them.. I think the server is a little overloaded at those times or something.. these problems do not occur on my other servers)
MAHC-1.3 Demo is online: here
(If you want to try out all the game features, etc.. and noone else is in the chat, try logind in twice (2 different browser windows) this way you can try games against yourself.)
