Check out RPGSolo.com!

During my vacation, I received more than one message about this nifty site. It's a new online tool called "RPG Solo." It's still in beta and more will be added to it, but it's worth a look right now.

From the site:

RPG Solo allows you to solo RPG with a Virtual Game Master. With this tool one or more people can play any genre of role-playing game without a GM, DM, or anyone being left out of the fun.

Check it out HERE. Hit "play" to test it.
