We are a training provider that have courses where there are no defined term dates for each student start or finish date.
So students can enroll and complete courses at any time (well, until we update the course and move all new students into the improved version).
We have also dipped our toe in the water of creating e-learning courses, selling courses through Catalog. Where again students just taking shorter courses may want to start and finish at different times.
So if possible it would be great to have the option to remove term dates not just have the "default" set and have an option such as not required.
