Privacy

We respect everyone's right to privacy and therefore we ask that members do not post personal details (such as contact details/workplace details etc) of either themselves or anyone else in a public posting. Please use the PM (private message facility to do this). Where we suspect that a member is using our PM facility to abuse the rules or other activities deemed derogatory to other users or the boards in general we reserve the right to monitor messages sent via the PM system.
