Unanswered Discussions

Allows users to see forum discussions that have gone unanswered
The Unanswered Discussions block allows users to see forum discussions that have gone unanswered.
Users can see:
their own unanswered discussions,
oldest unanswered discussions (posted by others), and
random unanswered discussions (posted by others).
News forums are excluded by default.
The block was originally coded by Samuel, a work-experience student under the supervision of Martin Dougiamas.
