Am I required to comment to mark something complete?

No. None of our modules require you to make a comment before marking the topic, lesson, or module complete. If you are having trouble marking something complete, it is likely due to a conflict with a browser extension you have installed. You could try disabling all of your browser extensions to resolve the problem or try one of the following strategies:

1. Access our site using an entirely different browser (e.g., Chrome, Safari, Firefox). See instructions and options. Using a browser that does not have the same extensions installed as your current browser is your best bet.
2. If you would prefer to use your current browser, open a "private" or "incognito" window or tab in your browser (instructions) and access our site from there. The private/incognito browser mode will usually clear your cache and disable most browser extensions.

If you continue to have trouble marking something complete, please contact us for assistance.
