donyusufahmed, truth be told it wasn't easy to understand you.
in my forum and i am trying to make it so that only "checked" member who have made at least 10 post in the forum can see the link.
I suggest you set the permission for various groups for this very board in CP->Forum » Management of forums and sections
i can only check off who i want to see the fourm but there is no option for post count
You can set it up in CP->Users » User groups » Auto-transfer->change Forum entries field from o to 10 and Save.
when i click on forum, my main buttons disappears, i was wondering why that is?
What do you mean by main buttons? Can you please be more specific. Provide a website name and the screenshot of the buttons that disappear.
