Not sure where to put this but since it's gaming related this looks like the right spot. I'd like to call to attention to:
http://roll20.net/Might be a useful tool for anyone planning on doing an online game but don't want to go through the hassle of trying to get maptools and OpenRPG to work (it's browser based) or deal with play-by-post. Only one person (the GM) needs to register really and they save the maps and campaign on the site.
