Ensuring your user’s operating system and software configuration are compatible with your LMS is integral to a positive and successful user experience. After searching for a low-cost solution and coming up empty, I developed a browser check tool for our university’s Blackboard platform and have found it to be invaluable in providing support to our users. In this session, I will describe the process of creating the scripts needed and how they work. All the Javascript, Java and HTML needed to build your own functioning Browser Checker will be provided. Script modification and customization will be discussed. Currently "BrowserCheck 2.3" checks the browser and version, OS and version, JavaScript, pop-up blocker and cookie settings, Java version, and various browser player plug-ins.
