As I've mentioned, Angela and I are planning on jointly running a game. We've both been part of GM teams in LARPs, but neither of us has done this in a tabletop setting. In some ways, I expect this will be easier. Communication should be simple, since we'll both be around the same table. That said, I'm wary of pitfalls such as inconsistencies in rulings and such.
If anyone has any suggestions, tips, or warnings... well... we'd be grateful for them.
