We have been using this software product since 2011, it has allowed us great flexibility when managing our technical documents within an organization as complex or small depending upon your needs! It's easy enough so staff can manage their own docs without needing support services but also provides full control over document versions/revisions allowing any level admin access at anytime (we are not limited by server capacity).
There really isn't anything I don;t like about how well designed all parts work seamlessly - which means we will never be looking elsewhere again if there was another better option available out-of-. This may seem strange given its size compared some other products such as Adobe XMPP etc however you get what u pay fer here folks!! Highly recommend giving them serious consideration especially now they offer free trials. Document Management System used internally where multiple authors need ability upload new doc version into repository then push changes back up once approved via check box approval.
