Intro campaigns?

Anyone interested in running any intro campaigns? I saw one that fired a while ago (13A) that was designed to help new players. If possible I'd like to join something of that nature. I can try any system but I'd need to buy a PDF before I play to get used to the system.

There is still a slot open in my DungeonSlayers game :-) And no need to buy anything for that, DS is free to play.
