With the new 2017 version, you now have 3 options to release results when you Start a secret Santa:
This is the classic one. The results are kept secret until D-Day. Each person only knows the results of their own draw. You can then gradually disclose them. The reveal of the results is done in 2 steps with the authorization of the organizer (choose "Edit" next to "Visibility of the results" on the "of follow-up of the draws" area):
It's simple, with this mode, the draw results are never revealed by My-Secret-Santa. Each person only knows the results of their own draw. This does not protect you of "leaks" of course 😇
With this mode, the results are revealed to everyone on both the participant area and the draw tracking as the draws are launched by the participants.
