Who would like a PM facility on CT

Hopefully, now that CT is over 1 year old,  Ro will specify a PM facility during the promised upgrade so that members can share personal details like arranging to meet at a particular site, or share humourous stories, just like we would while socialising on site, (site humour being slightly more adult than allowed here),  ETC ETC. The advantages of Private Messaging would be IMO a great asset to building on the friendliness engendered within CT.
