OU Blogs uses OU Campus pages to run a blog in your site. This includes not only the article pages but a listing page that dynamically pulls in each post. Other supported features include archiving, RSS capabilities, and filtering posts by metadata such as tags and author.
The module has its own section in your site, usually labeled "blog." Each blog post publishes out both a regular page and a data file. The data files are then aggregated by a server-side script and displayed on a listing page.
Because this is a highly customizable module, it's likely that your implementation of OU Blogs has some unique features that aren't covered by our documentation. For specific questions, consult your developer notes.
