I'm wondering if the OP was thinking he wanted to start a discourse with the poster of, or within a thread, but didn't want to do it publicly??? 

I'm guessing here, but I would suggest he click the poster of the info that he wanted to converse with, and send that user a PM? 

Maybe I'm reading something into it?

Martin, you da man, and everything you do is forward movement. Thanks for the place to shelter, and share.
