TL;DR: Quick Tips for Agenda Builder Sessions that allow enrollment ahead of time will show an “Add to Agenda” button. If you have a green “Added to Agenda” button, then you’re enrolled! At Dreamforce, you’ll need to show up 10 minutes before the session starts so that you don’t lose your spot. If you have a red “Limited Seating” button, then you aren’t enrolled. However, if you show up prior to the session, there may still be seats available. Bookmark a session by clicking the star. Bookmarking does not guarantee a seat in a session.
