Meetup.com allows people to search for groups by zip code. This is key. Specifically if people are wanting to meet in person, one must be able to filter the search by location. I don't want to search *members* by location, but *groups*. If Yahoo! had this option I would strongly consider moving my Meetup group to Yahoo!, since Yahoo! is free and Meetup charges by the month. As it stands the set up of Yahoo! is not conducive to local potential members even being able to find my group.
