We are ending support for SLS1, our current website system, on 9/1/2018, and replacing it with SLS2. SLS2 is certified as authoring WCAG2.0 (ADA) compliant content. Please plan to convert as soon as possible. You must convert by September 1 or get an extension by buying Service Blocks so we can help you with the conversion.
Moving to SLS2 means your sites will have a modern design that works well on mobile phones. Most important, though, it means that you can rest easy knowing that your sites are built on a system that is certified 508 compliant.
