How include small text file as a quote?
 

I'm using Slackware 13.37 in an EMachines machine. Which has begun
responding to my starting Firefox with a mysterious text file which
I don't understand at all. It starts, "INCLUDE ScriptlessBGT...."
and I can't connect it to anything I've done. I would like to put
that file here as a quote (it's not large) or if the above small
frag means something to someone, I'd like to hear of that. I think
I'm most interested now in: How do I do a quote from outside into
this message area? Thanks -- mha [Sat 2014 Dec 27]

Hit the "Go Advanced" button below- there you'll find icons that allow inline [quote], or an attachment.
