How do I add or edit the agenda?

You can manage your event's agenda from the Main Event Registration page. In your event dashboard, go to Event Pages > Main Event Registration > Agenda. Add your event sessions here, and organize them using tracks — a track is just a category for grouping related sessions (for example, a "Marketing" track for all marketing-related sessions). Turn on tracks when you want to organize multiple sessions under specific categories.

Note: on the Free plan, you can use up to one track; upgrading to Pro or above unlocks multiple tracks.
