[MRBS-general] restrict read and write access

[alois b. <alo...@sb...>]

hello list

I want to use the program mrbs, it looks very good and its wat we have
searched.
2 things would be nice if its possible:

- restrict the read access (now possible for unknown users ) to authenticated
users and possible for certain areas.
- restrict the read and write access for certain areas to certain authenticated
users  (now every authenticated user can write everywhere)

to implement this have i to change the code ? but where?
maybe somebody have done this or can give me a hint ?

thank you
