Things that Confluence Hosted Won't Allow Confluence Hosted has significant limitations
No clear information on how much data you are allowed. They claim unlimited spaces and pages, but 10GB limit on files, photos and videos
Can't add new themes
Can't add your own plugins
No personal spaces for individual users
Can not be firewalled for private inhouse use
No control over configuration and customization
No mail archiving
No user searching
Can't allow anonymous access, so hosted is probably useless for crreating a public wiki site.
Unknowns:
They don't mention group permission lists. On Confluence, these are only available for editing by global system admins, so they may not be allowed in hosted version.
API access is probably not allowed. API access would let you write scripts to manipulate your wiki pages.
