I think it's going great, but that might be because I keep getting paired up with the same people (I've been with cardsman 3 times and HalvSame twice) and we've had really productive exchanges. The complaints I've heard are from people who never exchange sessions with their partner. Not sure how to improve on this... make everyone post in a thread or e-mail you every time they want to be involved? Seems like a lot of work. Don't include someone after they've flaked once (or twice)?

One things that might be cool is to set up groups of three one week. Everyone could send one longish session (100-150 hands) around and then get two opinions on it rather than one. And it would be enlightening to see how someone else critiques the same set of hands.
