Just ran across these and thought you all might be interested:

"Wikihtml2man is an easy to use converter that parses HTML sources,
normally originating from a Mediawiki page, and generates Unix Manual
Page sources based on it (also referred to as html2man or wiki2man
converter). It allows developing project documentation online, e.g. by
collaborating in a wiki. It is released as free software under the GNU
GPLv3."

"For a while now, I’ve been maintaining my todo lists as backlogs in a
Mediawiki repository. I’m regularly deriving sprints from these backlogs
for my current task lists....A SpecialPage extension that I’ve recently
implemented now helps me through the process. Using it, I’m
automatically getting a filtered list of all “IMPORTANT:”, “URGENT:” or
otherwise classified list items. The special page can be used per-se or
via template inclusion from another wiki page."
Both of these are from Tim Janik of Lanedo. Thanks, Tim! (cc'd)
