To share phone numbers with whomever asks you for it. I mean, people you KNOW you can trust. I'm asking cause I have found myself with a question I need an answer to asap and don't know who to call. It would be cool if I had numbers of some guys on here so that way we can call each other up and talk and ask question. It'll be alot quicker than waiting for a reply sometimes. PMing would be the method, no public posting of phone numbers, of course.
