I don't hold much respect for commerical liers, nor unfilled promises, so I have to open with big thumbs down. Still, they have a very professional site as far as graphics and presentation go, and it looks good to be frank and they offer four catgories of hosting Business, Home Exchange, Gay and Backpackers. I wish I could say more. Read the notes under Servas below. This is a purely on-line service as far as I can tell.
Membership is free.
This club has over 2000 members worldwide. Which is about all I can say for it. It's on-line only, and driven by rather poor software alas. Security and features are about as low as you can get, and frankly it looks like a quick attempt to justify some banner advertising. I'd stay clear of the International Hospitality Exchange personally, as much as I hate delivering a bad review.
