Option 1 - Alpha guests can join an Alpha by visiting tryalpha.ca and typing in their city. They can search by language, age group, and radius. Please share the tryalpha.ca website with potential guests.
After guests click into a specific Alpha, they can add their name and email to sign up to attend. This will send an email to the Alpha contact person (more info here). The Alpha contact person can then email Alpha guests with the start date, time, and any key details to join the discussion with the group (see sample welcome email here).
Here is a SAMPLE course info on the tryalpha.ca website:
Option 2 - Create your own Guest Registration form (using Google Forms, Wufoo, Zoom etc) for guests to sign up to your specific Alpha course: more info here
