I've been using GTT now for a few weeks, and it would be nice to have an audio notifier (and possibly a more obvious visual one as well) that lets me know when someone's hand is raised, or an entry has been posted in a chat window. This would be similar to what is already done when someone joins or leaves the conference call. Perhaps it could also be done through the phone (organizer only) or through the local PC speakers.
This would be very helpful when I'm running a class of a dozen attendees for 4 hours, have several windows open on a dual-monitor screen, and especially with hi-res screens - to make it more apparent.
thanks,
Brian
