Faculty members, do you sometimes need to collaborate with colleagues or visiting speakers, providing them with access to your Sakai course or project sites? This brief video shows how to provide access to anyone, whether a colleague at W&L or someone outside the institution: https://tegr.it/y/ukea
In addition to the many academic tools available, you can use Sakai to: house documents and other files, accept submissions from site members, post announcements, email site members, maintain a calendar, collaborate on a wiki page or blog, and send out surveys.
Third-party tools like DropBox and Google Drive can also be useful for collaboration, but carry certain risks. See these guidelines for use of third-party cloud services, written by the Office of General Counsel: http://www.wlu.edu/documents/general_counsel/CloudComputingRisks.pdf
