I don't want to derail a thread but an issue regarding the PM system has come up in the Casboult thread.
The PM system is a private form of communication
The function of the PM system is to take off topic argument out of threads, or to provide confidential information that cannot be shared on the general forum.
Personal messages should not be posted on the general forum.
The PM system should never be used, and will not be allowed to be used, to abuse or threaten. If such communication does take place it should be reported through the appropriate means and examples given.
