The first thing you will need to do in order to see which sponsorships are available to your group, is create a group page. If your group has participated in a Pear sponsorship in the past, the already have one! Simply click on My Account to view them. If your group has not yet particiapted, please see the FAQs about Group Pages for more information.
Once the group page is set up, you can view all of the available sponsorships right on the page. Head to your group's page to check that out. :)
