Private messages

I have to start by saying I am not a computer guy, so please be kind.  LOL.  I am going thru my personal messages here and have discovered that I can only see the last message sent on each.  Is there a way to look at the whole thread of interaction in each message?  It is a bit frustrating because I have had some great advice that I am now unable to get to. At least, I am too dumb to figure out how to get to.  LOL.

I can’t tell you offhand how to do it but I believe everything is available but just laid out really weird.  The PMs on this site are unusual to say the least and sometimes even confusing.  I remember Denny sending me a PM and I responded but later I was looking at another PM and it looked like I had never responded to Denny.  My response was not shown.  But later I did find it so you just have to poke around and eventually all of your conversations will be visible.
