Hi guys, I'm quite new here. I know my question is going to make a lot of people laugh, but how do I private message another member of the forum here? He has the number of a sweet sweet girl.. 
As Steve Dave said, put in and you'll likely get the pm privilege.
But.... do you honestly think anybody is going to pass on a phone number to you?.... get her number the normal way, not trying to get it on the sly.
You could be bloody anybody
