How does one "invite" people to this forum?

[Kirk_Masden]

Here’s a link to a “badge” one can get as a result of inviting others to this forum:

https://community.appsheet.com/badges/27/champion

This badge is granted when you’ve invited 5 people who subsequently spent enough time on the site to become full members. Wow! Thanks for expanding the diversity of our community with new members!

Currently, only @Peter has this badge. Perhaps no one else has earned it because, like me, they don’t know how to “invite” people. Thanks in advance for any advice or instruction about how to invite people. I’d love to get that badge.
