Well, there's the frag list.
Ahem! Let me just say that that is not what I had in mind in post #18. It's not! I figured SteveH was speaking tongue-in-cheek when he said "it's for identification purposes only" and I was just bouncing off of that to indicate that I recognized the utility of having addresses to
write to.
Now that I've made that disclaimer...I'll just say the list may have more than one valid use.
