The link for the new chatroom can be found near the menu at the top, just under the "you have...messages" notification. After the initial "burn-in" time / testing is complete, this will become one of the normal menu buttons. In the mean time, please feel free to try it out and let me know if there are any problems.
The chat system uses Flash, so you will need to have Flash on your browser in order to use the chat system. If you don't already have it (you probably already have it), you can download it at

Please post any technical problems in the Technical Difficulties Reporting Forum, so that I may respond sooner. I'm on Holiday until early January, but I'll try to respond as quickly as possible.
Thanks -- and Happy New Year,
Allan
