Error: We’re trying to clean up some GEPs and get rid of ones we don’t need any longer. Can we do this by using only these permissions? If so, what exact permissions do they need? Also, is there a way to just do this with a specific page only? OR do we assign a responsible editor and then have them take it through a review using Workflow? Is there a better way to do this?
Solution: The Wiki is a "document workspace". If you want to get rid of a page of a part of a page, just delete it. The permissions always apply to namespaces (and in case of permissions set by RE settings also on pages). I think, if every GEP is modeled as a single page you should just have a review workflow be run on each of them. Your reviewers can then decide whether to keep or remove it.
