Lost your links?
A trip has two links. The organiser link, starting /o/, is the one that scores. The view link, /t/, is the one you pasted into the group chat.
Check the group chat first. Then sign in with the email you set the trip up with: every trip you have made is listed under Your trips, with its board link.
Otherwise, email hello@tourboard.golf with the trip name and roughly when you set it up, and we will send them back. Nothing is lost; the board is still up.
