Kinda customized to a specific need , think would leave out that feature.
Right now I am concentrating on the following extra features :
In no particular order :
1) Category View multiple pages
2) Comment on article
3) Rate article
4) Ability to create , edit and delete subcategories
5) Search
6) Category headings , like in the forums.
Probably not that soon though ... lets see what turns up as we go along.
