Yeah. I always reread the rules section if I'm unsure if I could post certain things. Studying law made me pay a lot of attention to rules and how it's worded.
I did read them, but I'm not a liar...
Of course no one's going to study the guidelines, and of course most rules are common sense, but you should make sure you understand the ones that aren't.
You should at very least take a look at them before you're going to do something that involves other users.
