Not putting pressure on people to enter the competition would help. If you're trying to encourage people along to the judging event, why not add it to the Beoir calendar?
I can't speak for anyone else, but I'm not interested in entering a homebrew competition. That's hardly an act of sabotage. And the same goes for joining the forum: I read too many forums already and [i:1lqw6co9]I'm just not that into home brewing[/i:1lqw6co9].
It looks like you're doing a great job of organising the competition and I genuinely hope it's a roaring success. But it's not for me and I'm a little uncomfortable that my not being involved is somehow being interpreted as a slight on it.
