Restricting Page Creation

[Dana Buxbaum]

Is there a way to restrict creating pages in specific spaces?

[Nic Brough -Adaptavist-]

Yes, you can remove a user's right to create/edit pages in the space.

I suspect you mean further down in the tree though?  That's a "no" I'm afraid.  Confluence is aimed at collaborating with people and blocking page creation within a space for a user who can create in other places kind of goes against that (although there are perfectly valid use cases, there's a strong argument for "your spaces are not organised properly)
