Forum typing question

[NorthLaurel]

How do I reply to someone's post so that the gray area with the persons quote appears. When I have been replying I delete most of what they write, but keep the few bits that I am referencing, but it doesn't do the nice gray area showing who I am quoting for me the way I see others having on their replies? Am I making sense?

This post I did on the desktop. I selected the 'Quote these posts now' and it inserts your post in the Quick Reply box. It can be edited from here to only include the relevant bits. If you type a reply first and then click 'Quote these...' it will insert it at the *end* of your post.
