In a thread I started in Quantum Physics section, the mentors implied that they wouldn't be discussing any issues relating to photons unless we had studied and completed the equivalent level of a Ph.d degree in Physics and had taken advanced courses in QED. I didn't see anything in the Guidelines about such an advanced education being required to discuss on this Forum, at least when discussing on a basic knowledge level. I don't know why but I assumed perhaps these Forums were also used by people either in university or having an undergraduate science degree or equivalent level of understanding. Could someone please clarify this and perhaps put it in the Guidelines. It's embarrasing to post messages only to be told how much of an idiot you are. It would be better to understand the rules to begin with.
