Thank you Microsoft for the TechNet articles that explains the Co-Authoring features with the 2013 SharePoint/Office and the 2010 versions. We find the grid on the bottom particularly helpful. We have found this feature an amazing time savings for integent! (as we use Project Server 2013 with SharePoint 2013) and we hear equally rave reviews from our Project Server 2010 and 2013 clients.
Find out more information on our Project Server services here.
Happy Reading …
