Feedback for the folding Editor
Many moons ago, I submitted patches for the cperl-mode in Emacs so that you could use Emacs as a folding editor. Today, I got my first unsolicited thanks for the effort: I'm teaching myself perl, and this editor setup will make the task more fun.
Ok, so it's not the most dazzling praise, but it'll do. It seems about half of the individual pages on this site have provoked some sort of email response at one time or another. That's pretty nice.
