[Mediawiki-l] Project/Task management

[Sy]

I have experimented with a combination of categorization and the
dynamic page list extension:

handy as it could be.

The WikiGTD doesn't work for 1.4, and I don't believe it's multi-user:

I was wondering what solutions people know of with regards to
MediaWiki as, or used by, a task or project management tool.
