Easy Rich...
Highlight the blue text required.. EXAMPLE:

"HIGHLIGHT THIS LINE WITH YOUR MOUSE RIGHT NOW"

then scroll down to the box that says "Quote the text blah blah" and click it.. that will put the quote in your quick reply box and should look like this:

[ quote]
"HIGHLIGHT THIS LINE WITH YOUR MOUSE RIGHT NOW"
[/quote ]


Now put the cursor to the right of the newly added [quot e] box and click on "My username" (The blue stu @: m developments bit on left below avatar) that should add my name into the quote and look like this:

[ quote]Stu @ M Developments,
"HIGHLIGHT THIS LINE WITH YOUR MOUSE RIGHT NOW"
[/quote ]

Then repeat for whoever else has fooked you off... erm, i mean you would like to quote

**
The spaces in my example are purely to stop it quoting. Yours will not have spaces.
