I once suggested an idea for a beginner tournament in Toganash's group. The result was that the tournament went terribly throughout its duration and never finished.
So, here, you don't need to ask for permission; you have to actively encourage people to actually do something. So, regarding "don't take on more than you can handle," I find myself laughing... if I don't take it on, who will?
For example, in the latest thread, I wrote openly: "if anyone suddenly wants to run a Tournament, feel free." The reaction was zero. Okay, so I did it myself, according to my own tastes. Yes, my tastes are specific – I choose formats that I personally enjoy watching as a viewer.
The same situation applies to the September Tournament – by that time, I will already be running Mirrors and possibly Thrones (skd has disappeared somewhere), and I really don't want to add a third tournament to that. Therefore, I would gladly hand it over to any of those who are unhappy with the rules of my Tournaments. Want it?
