The Quotes module allows users to maintain a list of quotations that they find notable, humorous, famous, infamous, or otherwise worthy of sharing with website visitors. Quotes are currently stored as pseudo-nodes, and users with the appropriate permissions can maintain their own list of quotes much like maintaining their own blog.
Administrators can define one or more quote blocks to display either the latest quote or a random quote matching certain criteria. The quotes displayed in each block can be filtered by role, user, node, or category.
Smileys is a text filter that substitutes ASCII smileys/smilies/emoticons with images.
This is a simple smiley-filter that allows the easy use of graphical smileys (or 'emoticons') on a Drupal site. It comes with a set of example smileys. An unlimited amount of custom smileys can be setup as well.
This is a wiki module. It implements a filter that provides basic structured
text formatting. Basically, the conventions (and much of the code) are taken
from phpwiki.sf.net.
