Hi Susan,

I'm not a "senior" host by any means! However, I believe that you swap should be dealt with in the way that you are most comfortable with. The only concern to be had is that everyone's email is current so that each member is able to contact the other for the mailing address if that is the route you choose. Otherwise, it's pretty much in you hands as the the method of swapping.

I, for one, am very much looking forward to this new exchange!

Best of luck deciding!
