Glow Blogs have added a new plug in that improves the accessibility. The Accessibility by UserWay plugin can be activated by anyone with Administrator permissions for you Glow Blog. Enabling this plugin will give your site visitors a button on the bottom right of your site that allows them to make changes to the how the site is displayed to support accessibility.
The Moray Digital Learning Team would recommend adding this plugin to any existing Glow Blogs to make it easier to access for all users. Below is a video that will demo how to activate the plug in and how it works.
