The general idea I have is for a weekly get together for the remaining weeks of the summer. Every week, one of the group will GM a one to two shot game in a different system. Systems can repeat, of course, but the idea is to have some fun in systems we don't normally play.  So, while I'm not saying no Pathefinder, D&D 4e, or D&D 3.5, I am saying we should try less mainstream systems like LoFR or SoF&I. Not that the system has to be obscure or something. Honestly, when your GM, just choose the system you like playing in the most or a system you just really want to try out or, you know, whatever you want to do. At the end of the one or two shot game, someone either volunteers to be GM next week or we rotate it based on some set order and then we meet next week for a game in a system they chose.  While not a hard and fast rule, if the person GMing chose a system with heavy chargen, its best to provide pregen characters. Also, the GM should PM all the players in a group a few days in advance about what system he plans on using as well as the general setting idea for the game. You know, so we can make our characters. Also, if you someone doesn't like the system or setting idea, they can decide in advance if they want to skip the session or not.  As I have a pretty open schedule myself, I'm not super concerned when we decide to host the game. Just post the times that are best for you and I'll try to choose the best schedule possible. That said, if someone's schedule conflicts with someone else's, don't take it personally when I make a choice on that matter.
