Hi guys, 

I don't know how to set up access for users for each category. 

For example: 

I have category 
A
B
C

Than I have user groups for each category like A-users, B-users, an C-users. User from user groups A can see only topics from category A. So, each user groups have permissions to see only their user groups. But when they clicked on Recent topics or Unread topics they can see topics from other groups. Even if they can´t see group in forum. And I do not understand how to set it up. 

Thanks
