Globe*Trotter, Xenolth's latest open-source project, has released version 2.0 alpha 1. (http://globetrotter.sourceforge.net)
Instead of your users simply tacking their personal regards onto the end of a long list of people, they can mark where they live on a map and then add any personal comments they have.
It benefits your visitors because they can easily read other's comments and add their remarks in a fun and novel way. It also benefits you, the webmaster, because more people will be likely to give you feedback and you will be able to see where your visitors are!
However, as the project expands the uses for Globe*Trotter multiply. Such uses include a teaching tool and product demo.
We also have a free (with no adds!) hosted version of Globe*Trotter available!
Notice:
PLEASE UPDATE YOUR GLOBE*TROTTER AS SOON AS POSSIBLE!! The previous version contained a potential copyright infringement which has been resolved in this version.
