As we slowly built our Facebook presence, our followers (measured as the number of page 'likes') grew steadily and the page now has over 500 likes (Fig. 1). With over 200 followers (around 12 % of our potential audience), our Twitter account (@Students of SETAC) follows a similar trend, with large peaks of the number of followers during or immediately following the meetings of our different geographic areas (Fig. 1).

In general, our greatest interaction comes from posts involving photos and links (Fig. 3). We have more page views when links and photos are posted (Fig. 3) and continued usage of the page (measured by the number of clicks) with photo posts. While not as prominent as photos and links, status updates, which can include announcements on job postings, SETAC-related opportunities, events, professional training courses, meetings, and upcoming annual meeting student events, are also resulting in strong page engagement (Fig. 3).
