I'm definatly interested in an exchange. However I'm cautious of signing up to something thats too much work on a regular basis.

I'd prefer if each exchange was a one off sign up (and I'd sign up again in a few months for the next one).

Also rather than sending to a large number of people, or even with the same small group, I'd rather swap with a different (random) small group each time, so I get to see as wide a range of stuff as possible
