I'd be up for another.

I'd love to get into a Grand Campaign Hotseat on the "ground floor".

I'd also like to get into an American Campaign.

I'd even play in another Hotseat that is the same campaign as ones I'm currently in but I would prefer if I am not the same faction if at all possible.

I will agree with Zim when he says that these don't take a lot of time. Or, if you want to get really involved with role-playing, diplomacy, and character development, they could take a lot of time. It's up to you.
