Category lists display each topic's 'description' ( teaser) CjForum Module
We'd like to see this ...
the first hundred or so characters of each Forum topic displayed underneath the post title, as it is done in CjForum Module
(with an ellipsis if the post has more characters than desired excerpt length...)

This feature is delivered in v3.1.0 release.
