Clinton:
The rule of 3 line sigblocks went out with 2400 baud modems and 20MB hard drives. Mine is very conservative (oops! the "C" word) by todays's standard. I've seen War & Peace sized sigblock on some usenet postings, where the sigblock was longer than the posting. (check out alt.fairs.renaissance)

Still, I am greatly befuddled by her reaction.
