I hope no-one will be offended if I speak plainly.
It goes without saying that people can do what what the hell they like period.
All I want to point out is that for me, organising the two tournaments thus far has proven to be one of the most stressful and time consuming things I've done. Far more so than anything I've ever done in a professional capacity (seriously). The greatest worry, amongst all others, I personally have had is PEOPLE JUST NOT TURNING UP. A lot of people commit a lot of time and energy for absolutely no financial reward and the idea that people who have made their friends, have had their fun, have done their competitive gaming time, would simply say "meh I can't be arsed anymore, sod the next gen of players, sod the organisers, and sod the hobby" is sort of soul destroying.
Please please please do everything in your power to attend these events. It makes so much difference to the organisers, the players, the sponsors, and the venues. And if everyone decides to down tools then these things will just die.
