[Pharo-users] Not Pharo related - how does one respond to a message

Please allow me this one non-Pharo message. I am not that familiar with these message boards. When I see a message that I want to respond to how do I do that? I've been going to my email program - hotmail - and pasting in the subject line - copying and pasting any text that I want to include in my reply - writing a reply and then sending it. I can't believe that there's now a much more efficient way to do this. Enlighten me, please. Dan
