I send the entire Thread to myself (or anyone else for that matter) quite often. It's easier than you people who use graphic browsers can even imagine.

I just press P and it says,
1 - Save to my isp's host drive
2 - E-mail the thread
3 - Print to the Screen
4 - Print to attached printer

That's the luxury of Text Browsing with Lynx.

If I had to do it with Netscape or IE, I would do as Joe just suggested, go to the Printer-friendly section and cut out what is needed, and send that specific portion.
