When you want to have a strong online presence, you often need two things: a fancy website system like WordPress and a smart learning system like Moodle. Usually, people put these systems in different places. WordPress goes on the main website, and Moodle gets a little home on a subdomain. But sometimes, you might think, “Why not put them together?” So, you can have your main site with WordPress and Moodle hanging out in a subfolder.
