The document discusses four free tools - Skype, Tumblr, Twitter, and Google Docs - that universities can use to improve communication and collaboration. Skype allows for video calls and file sharing. Tumblr and Twitter enable sharing of updates and ideas. Google Docs facilitates group work on shared documents from anywhere. These tools increase interaction among students and staff, and help publicize university events and information through social media platforms. Maintaining free access to these resources is important for universities to take advantage of evolving technologies.
