That works with a hand-drawn ticket, how does it work when you have to email people? Is it built into the e-form?
Hmm, for example.
I participated in the ACEO exchange. What does it look like? Those who wish to participate unsubscribe under the post (exchange administrators, too, if they want), then the names of each participant are driven into the window and distributed among themselves (this is done by the admin/organizer). Usually, the profile name is indicated in the questionnaire to fill out so that you can send the form.
Of course, the organizer knows who is drawing for whom, but he is the only one who knows his recipient. For the rest of the participants, it works as it should. Questionnaires are sent to participants in personal correspondence, because not everyone will give their email to strangers.
This also makes it possible to deny participants a future Secret Santa if they received art but did not draw it to another. If the organizer did not distribute the recipients, he would not be able to track the honesty of the exchange.
