Always show description
The documentation 'Always show description' does not seem to be accurate. It reads in part:
"This setting is used in conjunction with the Allow submissions from setting. If it is set to Yes, the assignment Description will become visible to students at the Allow submissions from date. If it is set to No, ..."
BUT, if this setting is enabled, then the Description will be visible to students even prior to the "Allow submissions from" date. So the above is not correct.
Another issue is that there are actually no "Yes" and "No" options with this setting; it's a checkbox.
