I'd appreciate it if you'd take a second and introduce yourself. I'm mostly just curious who is using tcptrace and what they're doing with it. It's not a big deal and I certainly won't force you to do it, but if you wouldn't mind, please send me some email at tcptracehello@picard.cs.ohiou.edu. I keep a fairly quiet mailing list of tcptrace users that I populate with all of the folks who've contacted me via email. If you don't wish to be on it, just say so in the note.
