I've got my usr groups and users set up. If a user group has permission to post to their assigned categories "add a new item" is visible on the front end category pages for all categories not just the ones they're allowed to post to... how can I hide/show this links on the category pages depending on the group's rights that he user belongs to .

This is my problem too and I replied on another thread that has gone unanswered - pretty serious problem...
