Every member has an invite link. When someone signs up with it, they show on Invite friends, and you get an alert. A community stamp unlocks later — when they finish a 1:1 swap or a circle envelope. Signup alone is not a successful referral. Hosts can see who invited whom on the members list. Sharing a link never shows your street address. There is no cash bounty and no paid membership for invites.
- Open Invite friends (More menu, Home, or My profile) and copy your personal link.
- When they join, say hi in Introductions and point them at Classroom → Your first week here. You are not owed a swap. Same age-group rules still apply.
- When they mark a swap complete or a circle envelope received, you get an alert and the matching stamp: Brought a penpal (1), Three friends mailed (3), Five friends mailed (5).
Do this next on Invite friends is the coach line: share the link, welcome them, or wait on the next stamp. Classroom → Invite a friend is the course for inviters. Fake accounts to farm stamps can be removed.
