Now that Cover it live has gone to a pay system that can be rather costly, I'm going to try out a couple of different chat services for use during Arch Madness. I asked for suggestions and AIM seemed to be the most popular, but the drawback appears to be that you need to have an AIM username to participate (which only takes about 10 secs). I am trying it out presently - MVC Chris is my handle (or email: chris@mvcfans.com) is my handle. If anyone is online and wants to assist during this mini-test, let me know.
Otherwise, if you are familiar with another chat service that might work better, I am open to suggestion.
