I'm a distance learning coordinator and new to Moodle. Currently, I work with Canvas LMS and wanted to expand my knowledge on other LMS systems. Does Moodle offer a test course for new comers?
You don't need to sign up for an account. There are already working demo accounts there. It does re-set every hour, though, so if you want to do more long term exploration, you may need to do the next step, which is to download a desktop version for yourself here: Moodle downloads.
See the special links in the directions at the top for Windows and Mac versions. I'm a Mac user, and the desktop installation for Mac is very easy and straightforward.
