Topband: Proper posting etiquette

[Mikek]

Could someone send me an email on how to properly respond to someones post.
I'm used to Usenet where I just post my info below the previous response.
But, in that case the text is already there in your response.
  Do I copy and paste the previous post below mine? Is there a line to click
that copies the post I want to respond to. I'm missing something.

                           Thanks, Mikek
