Hi rowlets,
I'm glad you enjoy these events, and I'm sorry that you only discovered the information about the club proof requirements after you'd finished your round. Unfortunately, that's pretty much the situation we're stuck with: I post a Forum Thread in advance hoping people will see that, and put it prominently on the Leaderboard hoping people might view that before finishing their rounds... but for most players, I fear it ends up being the once bitten, twice shy rule, and that one knows to do it the following month.
I have forwarded your suggestion of an in-game note on to Shoe. However, I suspect such in-game notes are only available for everyone present in the game client in any mode of play, and not restrictable to one particular tourney.
The reason why we ask for screenshots or video proof of clubs used is that, sadly, the Club Restriction Programming doesn't work as it's supposed to.
Please see this post that I've just added from a prior event which hopefully will explain all.
Thanks,
Corwyn
Edit: Thanks Mags, for stepping in with an explanation too... while I was in the middle of my interrupted reply
