(yes, I asked them there too)

Anyone know of ones I can check out?

Thanks!

PS - I want one for my own use... not an "offsite" one like frappr.

Here's some:

Will look for more later.

Thanks, LT! I see now, I was searching "member map" and finding little. I didn't know that guestmap was a better term.

I like that first one you linked to. I'll check it out first.
