While I see the basis for adding a rule against this (especially posting complete e-mails), it results in some lost opportunities for useful discussion. Suppose someone has a conversation with their professor and comes away confused. They would like to get help here. Normally, when someone asks : "I read/heard xyx and I am confused" we ask for reference so we can see the context. In this case, the rule prohibits them from providing context for their question. Can any administrator suggest how to proceed in such a case?
