Someone offered something on WhatsApp. Can I list it quickly?

Yes. On Drop or Collect, tap Quick list. Choose item or service, paste or type what you were told into the one box (the first line becomes the title), add the area (suburb or city only, never a street address), one photo if you have it, and a phone number. You can add more detail afterwards.

This one applies to: I want to help, I run an organisation, I work at an organisation.
