You first need to come up with a proposal in writing to submit to the principle on what the group will be about,,where it will be held,what days it will take place,how long will the group meet for,who is in charge,will the school provide a budget or will the group raise money..Most school groups require a teachers presence so see if you can find a teacher to volunteer his or her time.I would have all this typed up and ready to be handed to the principle.Have some members of your group schedule a meeting with the principle, PTA or school council.I would have everyone in the group speak about what your group will be about and what your goals are for the group and how it will benefit the students.

Just get a couple of good friends of yours, and make them bring their friends, and hangout with each other everyday. My friends and I made a girl group that consists of 9 girls without even realizing it! We just hung out together at lunch and after school everyday. One day, one girl had detention, so she couldn’t go out to recess, and almost everyone told us “You’re group isn’t comnplete today!” and we were like “group!?!” and they said “yeah, you girls are attached at the hip or something.” And then we realized we were a group!

Make posters around the school, handouts at the office for a meeting after school one day

post myspace bulletins, tell everyone on yahoo, aim, ect, email everyone whos email u know from school and say to pass it on to 3 more people
