In administering Articles - if you create a topic and
set the permissions so that only a particular group or
groups is able to see articles assigned to that
topic... the module last_articles no longer displays
the titles of these articles - even if you are in the
appropriate group and can view the actual articles.
This is not a critical problem - but when the wiki is
the home of your tiki site - users won't see when new
articles are posted for them. This effects versions
1.8.1, 1.8.2 and 1.8.3 at least.
