Dave, You've very likely thought of this, but it might be a good idea to
restrict the info in any such listing to protect individual's anonimity.
Otherwise, you'll likely have fewer owners willing to submit their TZE's.
Remember, there's a lot of "non joiner" owners out there.
Also, I suggest we all travel with a small supply of fact sheets /
application forms for the registry. They're really useful if the owner
isn't around or needs to think about "joining".
