Hi May,
If you are referring to only permit super users to create events, pages, groups, you can just disable the profile type ACL at the backend to create these cluster items(groups, pages, events).

All other users would not have the permission to do so after this. However, super users will not be affected.

Thanks Raymond,
Btw, What's the different between Page and Group?

Hey May,
Perhaps you can refer to this thread. I have summarized the differences between groups and pages there.
Hope it helps.

Thanks Raymond.

Hey May,

You are most welcome. Glad I could help.
Feel free to start new threads if you have any other issues. I will lock and mark this thread as resolved.
