I have tried to find a list of what some of the abbreviations are here at PC. Is there one? If not I would like to suggest that it would be helpful for new members. It is easy to assume that using an abbreviation will be understood by everyone that reads it.

For new members it can also be very intimidating when posting for the first few times because you might use the wrong one. Example: Previously I knew and used pp for what is pdoc there.
