Only Admin can post in forum
 

Hi,
Sometimes I have like important posts that members don't get a chance to see because other members are so fast in replying or posting themselves. The last 10 threads or the statistics are not enough because they get full with other posts.
I went to the user group access rules but it's a bit confusing and tiring. My request is some kind of product or plugin that allows me to switch posting to only the group I desire and stop the rest for the time I chose.
Hope you guys got my meaning. Thanks.

you do not need a mod for that, just remove the "can post" permission from all the user groups except Admins

I did that but they are still posting. I can't understand it. I am going nuts here.
