Students won’t be in college forever and those who are more deeply involved in the movement tend to continue their activities after graduation. Therefore, it is a good idea to encourage them to become members of other organizations in the movement.

Many offer internships and job opportunities that may be very appealing after graduation. Some also offer reduced or free memberships for college students and alumni. Some of these organizations provide students with grant opportunities, speakers, legal assistance, useful materials, personal assistance, and guidance. Many also hold annual conference and retreats, and send out newsletters and/or magazines to their affiliate groups.
