Until now, I always thought that when you enter a place, you should take the trouble to ask if there were any rules, where they were written, and how to ask for something you might need (because there is no Santa Claus here and it's not Christmas every day, every moment).
It's not just a matter of etiquette. It's the very meaning of community: what do you bring to the others. It doesn't have to be a link to software, music, a book or a movie. It's also a help, a care for others. An attention to the community.
In my opinion, if you haven't read the rules, it's often because you've never cared about the activities of the community, about this place called "Community activity" for example.
I have read that they advise, for example, to automate by setting up an automatic alert/sanction system: you are level 0, you are deprived of something. No need for human intervention (implying "why on earth would we need moderators?") Let's all turn our heads elsewhere, the machine will do better than us.
But what is to be asked is not only to read this damn rule about the requirement of a help, a contribution, a positive gesture, as a prerequisite to a recognition by the community and the openness to the benefits brought by the community, by each one of us who does, contributes, shares with the community.
If I insist, it is because the real rule, the one that underlies the common effort made to build a community, that we must read what is written in our exchanges. The rules are only part of the equation. They are not the soul of the equation and there is no need to use brutal tones to exchange.
