For all teachers, educators, and school or district IT administrators.
MS just released Office 365 for educators. I would highly recommend this to any school. These are cloud services with extremely reduced costs (or FREE), saving your district money to put more of it into the classrooms. Class/staff web sites, public web site, online file storage, email (outlook), MS Office (w/ web apps), Instant Messaging, phones/voicemail (VOIP), calendaring, task mgmt, web search (of all curriculum/documents you have access to), and real-time collaboration (x people work on 1 document at once). This includes SharePoint, which is the platform of choice for collaboration and content management solutions. I would recommend engaging a competent solution integrator to migrate and deploy to Office 365.
