While the majority of the Yahoo! Groups team is working on strengthening and improving the core Groups product (more on that to come soon), a small team of folks have been working on a new way to create features within Groups, features that can be customized by moderators to fit the specific needs of their groups.
We’ve been calling the work this team has been doing “Groups Labs”, and we are excited today to announce the first new feature (or “grouplet”) built using the Groups Labs framework: the People Map! 
What is People Map?
Have you ever wondered who the members of your group are and where they live? If so, you’ll want to try out the People Map, which offers a simple way to add people to a map.
But the People Map is more than just a way to map member locations. By giving group owners and moderators the ability to customize the questions members are asked, the People Map can also serve as a dynamic group address book or even a group specific profile.
Learn More About People Map
You can learn all about the People Map, including how to link your members to it during this limited Beta period, here: http://advision.webevents.yahoo.com/peoplemap/
Please keep in mind that we are in the early stages of a first beta, which means that there are lots of kinks still to work out and improvements to be made (you can click here for a list of known issues with the current release).
People Map Feedback
So if you want to wait for a later release to begin trying it out in your groups, we understand. Nevertheless, we do think the People Map is ready for lots of groups to begin using it, and we look forward to the feedback from those who do. In fact, we’ve created a group specifically to collect this feedback.
We look forward to hearing what you think.
Thanks!

P.S. You can try out the People Map (from a member perspective) in the Moderator Central group.
