For those looking for an easy way to set up a simple course site, the MLA developed a theme for Humanities Commons sites: Learning Space from the MLA. Check out the Learning Space Demo site to see the theme in action.
The theme provides spaces for lessons, assignments, course documents, and events.
When you create a site on the Commons, check off Is this a course site? and the theme will be active on your new site. For more details about how to set up a site using the theme, see this guide.
