I first focussed on getting things working
Now that they do and we know what tags there are, I put some thought in providing better names
I use the form <what_it_controls>_<what_it_allows_you_to_do>
:statuses_read => :messages_read
:status_delete => :messages_delete
:user_read => :users_read
:user_deletion => :users_delete
:user_activation => :users_manage_activation_state
:user_invite => :users_manage_invites
:user_tag => :users_manage_tags
:user_credentials => :users_manage_credentials
:report_handle => :reports_manage_reports
:emoji_management => :emoji_manage_emoji
