I know that some of you have expressed interest in MapTool, but haven't made the jump over to the forums to sign up so I figured you might be interested in at least seeing how it works and how to get started with it. My current GM, Brad, has created this series to do just that. The nice thing is it will allow you to get an idea of what a VTT can do and what all the buzz is about if you have been considering making maps or adventures for them. Note that this is just one available tool out there, but most of the best ones have very similar features. To get the specifics you should visit the individual apps' websites/forums.

Hope this proves useful to some of you: http://www.rptoolstutorials.net/
