This isn't a voting forum, and we weren't asked for a vote either, but 
I just want to make it clear that just because I didn't say in a mail 
whether or not I thought REs should be in CSS doesn't mean I don't
have an opinion!

For the record I don't think REs are a good solution for CSS. Just
look at this thread: at least two of the RE experts got the wrong
answer to to Bert's original question (and I was one of them).

And now, to lighten your day, here are the regexps I used to match email
addresses and URLs in order to make them clickable. The files in this 
case were 300 submissions to a conference, and the regexps for the
mail addresses were heuristically built to match what was in those


 sed '/mailto:/!s/[a-zA-Z0-9][a-zA-Z0-9+\\._\\/\\-]*@[a-zA-Z0-9\\._\\-]*[a-zA-Z0-9]/<A HREF="mailto:&">&<\/A>/g
      s/\([^"]\)\(http:\/\/[a-zA-Z0-9_\\.\/~\#\\-]*[a-zA-Z0-9_\/]\)/\1<A HREF="\2">\2<\/A>/g
      s/^http:\/\/[a-zA-Z0-9_\\.\/~\#\\-]*[a-zA-Z0-9_\/]/<A HREF="&">&<\/A>/
      s/\([^"]\)\(ftp:\/\/[a-zA-Z0-9_\\.\/~\\-]*[a-zA-Z0-9_\/]\)/\1<A HREF="\2">\2<\/A>/g
      s/^ftp:\/\/[a-zA-Z0-9_\\.\/~\\-]*[a-zA-Z0-9_\/]/<A HREF="&">&<\/A>/g
      s/{\([^|,;@}]*\)\([|,;][^}]*}[ ]*@[ ]*\)\([a-zA-Z0-9_\\.\\-]*[a-zA-Z0-9]\)/{<A HREF="mailto:\1@\3">\1<\/A>\2\3/
