Sigh, my geriatric computer shows its age again. I just tried out the site and our campaign and got a notice that I'll need the latest version of Flash in order to access the video chat portions. Unfortunately, my operating system doesn't support the latest version of Flash.
I could try my wife's computer... but she doesn't have a webcam (there is a microphone, though...).
I may experiment a bit more, though. I just remembered that I do have Windows XP on a tiny partition on my laptop, so I might be able to get it to work under that... something to try later tonight. I'll keep you informed!
