The way I understood it a hive-#00000 account is a community account. Right now there does not seem to be any difference between my test community (Just Because), and OCD or GEMS. If I log in my community account as @hive-185849 I can vote, tip and delegate, any votes/comments would say @hive-185849. And the paper did state that:

The naming of communities is not exclusive and multiple communities may have the same or similar names; their base account is set by a hive-000000 name-number naming convention

So a fix I think is needed for the V.3 communities section, or at least some clarification on the monetized or not monetized standing.
