Thanks in advance for any help. I need a module/cms that does this, I have tried a few XOOPS modules but haven't found what i need.

I need to have articles, these articles can be rated by users and user can also post comments to the article. Articles need to be sorted either by subject, or rating.

Also these articles need to be by sections/categories in this way

Category
--Subcategory
-------Sub-sub category
-------------articles
-------Sub-sub category2
-------------articles
--Subcategory
-------Sub-sub category
-------------articles
-------Sub-sub category2
-------------articles

Easy to use and ease for posting articles a big plus. Hope people can understand my diagram

thanks
