Are you getting more comfortable finding your way around the course? It is similar to a webpage or blog, in that it has links at the top under the title that take you back through the hierachy of the pages, and then links along the left hand side bottom, that give you the main course topics. The comment buttons are easy to miss because they are gray and at the top right of the pages. Each task has its own page and so it has its own comment button. The comments and replies then show at the bottom of the page like you might see in a blog. Is this helpful?
