I added rel="nofollow"
support to the Blosxom writeback plugin. I use Doug Alcorn's version that supports
a blacklist and emails me when a new comment/trackback is posted.
Only one small change was required. I simply modified the writeback plugin to
prepend all href attributes with rel="nofollow".

Updated: changed regex to match word boundaries around href.
