Another request:
To have separate user rights per each user. I want each user to have write rights to his own category and not to be able editing other categories. Now this is somehow possible per Joomla group rights which is not convenient and flexible enough.

Colin might be able to help you with this; he knows a lot about access rights. I will give him a hint.
Hi
This achieved by setting the Access Level to the individual user.
See article

This gives some clues to setting up the restricted access to individuals.
Another article is "How to Create a Private Category"

Having looked again at these articles the topic would benefit from a separate article
@Ivan,
I'd be interested to know exactly what you're missing. That's the only way we can improve it.
