The space owner, cannot manager users watching all blog posts in their space.
Space owner can only manage watchers of specific pages/blog posts in that space.
Many users only watch the blog for keeping up with the news in the space and not the actual content.
We have a JIRA space in our Confluence instance. This space contains all system and operational documentation of our JIRA instance. Information not so interesting to the organization. However, the blog in the JIRA space is used for information about upgrades, new features, downtime etc. This is very interesting to the users. Therefore the users only watch the blog of the space and not the space itself.
Add the ability for the space owner to manage all blog watchers.
