okay… I am building a day care website with a public front end and a Parent Zone.  The Parent Zone will be authenticated users only.  There are two types of users (besides the administrator) who will have access to the Parent Zone — teacher type and parent type.  There are 5 classrooms.  Each classroom is a post category.  So here is the configuration I want.

I have 4 categories - A,B,C,D

I have 4 teacher user groups - A,B,C,D  (the users assigned to any of the teacher group should be able to edit, delete, add posts for the corresponding category.)

I have 4 parent user groups - A,B,C,D (the users assigned to any of the parent group should be able to view only the posts for that corresponding categories only.)

So for example, Users in Teacher Group A and B will be able to manage posts for Category A or B, but not posts for any other category.  Users in Parent Group A will be able to view posts in Category A.

There are also two other categories that have general viewing privilege (public) and general viewing privilege for all subscribers (or parents).

Currently, I have it set up such that the users who are in the teacher groups are set up as wp-editors.  

I have two problems with my current configuration:

1.  When a teacher in teacher group A adds an article to category A, all the other teachers can edit it.

2.  When a teachers in teacher group A adds an article and assigns to Category A, the system is showing the article as uncategorized.

I think the two problems are related.

Please help.  What is the correct configuration?
