I use the site news at the frontpage as a newsletter. I would like only to have one user to manage this section.
The problem i have is that now all my students and teachers can do this and i cant control this
First of all, thank you very much for your promptly asistance.
I ve done what you told me but when i logged as a student that have NOT been entered via site admin>users>permissions>assign system roles , which is enrole in a course when it enters into his session he can add a topic and also he can delete what i write.
I configure me as the front page admin, im an admin user also
