I think regardless of the format it is important to send reminder posts 1 or 2 days before the actual tournament day. Maybe that was one of the reasons for low attendance. I also missed them.
And regular intervals would be important. E.g. why not already post the schedule of dates in this post already, if you know it?
I personally prefer prices in Hive or HE-tokens over any NFT which is cumbersome to sell.
