Here are other suggestions to think about:

-Have you talked to that other person about your ideas? Get together and think about how you can get other people interested in your group.

-Check out this page: http://www.dreamactivist.org/resources/
Read with your friend the "Lobby and Organizing Resources from the United States Student Association". That should be a good resource on how to get involved as a group of organizers.

-Keep checking the thread you made to see if other people are interested or have ideas for you.

Hope this helps. Please keep in touch about how your group is going. I'd be interested to know more!
