First, click into the desired event date. This can be done from a few places, but the simplest way is from the "Events" tab on the left-hand navigation bar. Click the desired event date (it will light up in an orange box). Next click the "Menu" button in the top right corner and select "Register Attendee" from the event section.
Add the registrant's information into the popup window. The only required fields are First Name and Last Name. However, including a Phone Number and Email Address allows LeadJig to send messages to the registrant.
Click "Save Contact."
