I know of two good teams looking for 1250 Doubles practice this Thursday. I'd simply pair them up against each other, but it'd sure be nice to throw them an unexpected challenge!
If you want to coordinate a team with someone, you've got a couple days notice to get your lists together and get them tournament legal. If you want to just show up with any ol' 1250 points, that's perfectly fine too. In these matches, moving models around as a team is more important than simulating a tournament.
