General Actions:
"Detailed" rights are related to a specific part of the system or user activity, e.g. launch campaigns, possibility to create an invoice, target plan to the channel..
Global rights are superior to Local rights. For example, if the user doesn´t have global rights for sites preview, he cannot see the item Sites and cannot create a site, or generate statistics.
New users have local rights set by Preset rights.
Local rights also determine what campaigns/sites/channels/teams has the user acces to. The smiley icon in local rights of user and summary of campaign's/site's user informs about access to campaigns/sites/channels/teams.
