The most important advice I could give people is simply to avoid speaking in an angry and accusatorial way. Example #1: "The SuchAndSuch part doesn't seem to be working, and I can't make a ship fly with it." Example #2: "The SuchAndSuch is badly broken, and it was irresponsible and lazy of Squad/ModMakerDude to put this piece of garbage out this way." Both convey the same message. But one is likely to lead to a productive discussion, and the other is just going to invite more angry complaints. There are people who will object that this is sugar-coating and self-censorship, but really, it's a matter of enlightened self interest. Would you rather get a moment of pleasure out of saying something nasty, or post something that's more likely to get your problem fixed?
