with the ability to have more than two people involved in a private exchange WHAT!?!?! Egad! I did realize it was like a thread, but...I'll have to go and see if I can figure out how a third person could get in there. Man, that is weird!! Sheesh, the things I don't know could hurt me...
I'm still embarrassed about the time I (very belatedly) found out that my random Reply-to-whichever-post-was-at-the-bottom-no-matter-which-post-I-was-actually-responding-to was messing up the threadnodists.
