If you're interested in promoting your group, you can find great tips and ideas in the Groups Resource Center. Owners and Admins of some of CafeMom's largest and most active groups are in the Groups Resource Center and they have tons of information to share with new group owners.
Along with joining the GRC, here are some other suggestions:
1. Create a Signature that links to your Group. Everytime you post, members will have a chance to learn about your Group!
2. Invite new members to join your group.
a. Click on "More Admin Tools" while on your groups homepage
b. Click on Invite Members.
3. Post a link to your Group on The Newcomers Club Recommended Groups thread.
4. Use the Mom Search to find Moms that may be interested in joining your Group.
