Do they have the know-how? Because the only one trustworthy person there is Alien aaand maybe Death too.
The only people who know real "know-how" are those who never share knowledge or those who cheat themself, making undetectable reply software and other bullshit. Even I have nothing against creativity but if someone makes cheated times as legit it's like being 100% fully healthy a human being, take part in the Paralympics and BE PROUD THAT HE WIN !!
Please don't expect some "AL|EN magic wand" - there will be scripted, cheated and boted demos at DFWC. Noone should have less fun because that. The fact that somebody will send them also prove that they are looser in the first place.
