I have created a web application called Wikilist.
Wiki List is intended for sharing information that's formatted as ... lists.
It is written in PHP/MySQL.
Wiki List can be downloaded from here http://www.info.org.il/english/wikilist.html
[You might wish to change 'laid of' in that page to 'laid off'.]
p.s. It's actually called WikiList, but this wiki already has a page called WikiList so I had to un-capitalize the "L".
