It has been a couple of years since I was on Yahoogroups but I never had any problem. I do believe that Yahoo has a chat like AOL's Instant Messenger or MSN. Those would be something you have to install on your machine and different from what Mugsey is using for the group. Also is different than the Java Chat provided for each group. Got to run to work so Mugsey when you are ready, lets recreate a mystery! :-) PS let me know if you change but set up on Yahoo is fine with me.
