http://www.pingjockey.net many WSJT users on that page and it has a chat mode to set up skeds very easily.
And for those that have not tried meteor scatter Joe's WSJT software really make it nice and simple. WIth the cost of his software being $0 there is no excuse to at least try this mode. As long as you have a VHF SSB station, a computer, and sound card interface you have everything you need.
I was able to get into MS for just under $19 (my parts for the sound card interface). Where else in ham radio can you try something new that costs basically nothing to try?
