Well, not me, because I can't get it to work on my end, but I have a feeling there are others about who are better at these things than I am. What I would do is let people know when you will be there (time and time zone) and see what happens. Something that worked pretty well in other groups I've been involved in was that there was a standing "date" for chats so that everyone knew on that on a certain day and at a certain time for a couple of hours, people would be checking out the chat room. Could work here. :)
