Details of my proble:

- I have 5 custom groups and all groups will have multible registered users (this is extranet site)

- One user can belong to several groups.

- Users will be allowed to read articles for concerning their own group(s) AND all the common articles.

- None of the users are allowed to write or modify the articles.

- I have used original joomla articles AND K2 articles. -> This system should work in both article managements. (If it is not possible I can order to use only K2 article management.)

 

Question: How can I control the users with K2's user-controlled adaptation? Now it is only possible to assign permissions for groups and there is not 'reading permissions' at all. Does anyone know any extensions that would do the trick?
