When you go to Meetup.com, near the top of the page there should be text saying "Find a Group". Click on that. You'll be sent to a page with two main text boxes. One is for the kind of group you'd like to find - be it a mommy group, a playgroup, a bunch of people who want to get together and discuss the flavor of cheese all day. Type that in. Add your zip code or city. Hit "search". It may take a couple of tries on the "type of group" to get the right wording to find the right group, but you should find listings for types of groups. Join the one you think works, and start RSVPing and attending meetings. Some groups charge a low member fee, because Meetup charges groups about $70/year for website maintainance. Usually you have a grace period to figure out if the group is right for you or not. I know I've really enjoyed my group; it's huge and there's always something being organized - and we're able to organize our own stuff within the group, too. I've found some great mommy friends this way, and my son's made some good friends too. Good luck!
