ISO means “in search of.” Looking for lists what you want. Have to send lists extras in your stash. Both show on the ISO board (tabs) and on swap threads so packers can match. Looking for and Have to send stay in your age group (hosts can appear on either). Matches you lists people whose words overlap yours — you have what they want, or they have what you want — skipping mixed-age pairs, country-only mismatches, and anyone you already have an open swap with. Home also shows a few of those matches. The ISO page says Do this next. Suggested penpals still score the same overlap plus tags and mail pace.
- On My profile, fill Looking for (ISO) and Have to send.
- Save — you appear on the matching tab while you’re open for swaps.
- Open ISO — Do this next points at a same-age overlap. Request swap on the card; the note starts from the shared words. Street stays locked until they accept.
Please avoid still wins. Classroom → ISO and your stash is the short course. Packing this week is a signal you’re assembling mail now, not a mailbox pause.
