Hi, as it is being discussed today, I would like to ask about how to post correctly on physicsforums.com. I re-read the (updated?) agreement today, and I found this rule about where to post questions. I am still an undergraduate (I think, the levels seem to be different in different countries; I'm in the 4th year of engineering physics), so naturally I now and then come up with questions on the course material. Sometimes I post them after thinking for a while, allways asked in a way looking for an understanding of the subject, not just the "correct" answer. According to the rules, such questions should be posted in the homework section. But if you look in the homework/advanced university section, the questions seem to be of the not-so-advanced kind. And the same goes for the "general" forum; the questions arent exactly allways on the graduate level. Now I think there seems to be a big difference between rules and practice here, or have I read the rules too serious? And what should my personal policy be? Should I take "graduate" just as serious as when I see it printed on a book used in many 3rd-year courses?
