You can use Falklands Market messages without setting up any extra contact links. Messenger and WhatsApp are optional. To add Messenger later, open Settings → Social Links and enter your own https://m.me/your.username link in the Facebook field, then save. Use your Facebook username, not your display name, and check that the link opens the right profile. Save it once for your adverts; clear the Facebook field and save to remove it. For WhatsApp, add the number registered with WhatsApp, including its country code, tick WhatsApp and save your account details. These contact details become public. Messenger conversations may land in Message Requests. Conversations in WhatsApp and Messenger take place outside Falklands Market.
