If the event is private, grab the passcode emailed to you from the organizer before you proceed.
First, navigate to the "Event Tab" on Hio, which is the calendar icon on the bottom navigation bar (second from the right).
Then, search or filter the events to find the event you want to join and tap on it.
If an event is private, you can join it by typing in the passcode which was sent to you by the organizer via email (if applicable), or by clicking the link which was sent to you by email from your event organizer. That link will take you directly into the event and mark you as "Joined."
If the event is public, simply tap "Attend Event" and you'll be entered into the event to network!
