The 508 Universe serves as a central hub for GSA's section 508 training and information resources. It includes each of the topic-specific courses that address 508 implementation as well as web links and a glossary of 508-related terms. First time users of the site will be asked to set up a username and password. No additional information is required in the registration process, nor any identifying or personal data. The username is used to track the user through the courses allowing the user to leave a course before finishing it, then can choose to "resume" when next entering the Universe without starting from the beginning. This eliminates any possible security risk of using cookies, and no files are written to the user's computer.
