I have been the social media manager and content creator for the Instagram of Gorillas in Your Midst, a peer health education group, since August 2014. The Instagram account was created, but had not been active for over 6 months. I rebooted the channel and increased our following from 21 followers to 235.
I conducted contests through Instagram by having students that came to our programming and events take photos with our white board and post them on social media for a chance to win prizes. I also conducted a contest in which students had to find Gorillas in Your Midst members (they wore GIYM t-shirts), take a photo with them, post to Instagram, and say how they do the gorilla thing (do the right thing). Students who found members won a "do the gorilla thing" tank top.
