Please remember that the schools can't provide technical support for the applications. Both Common App and Coalition App have links on every page for submitting a help ticket. What's more, it's helpful when you alert their teams of parts of the applications that aren't user-friendly, so don't hesitate to reach out to them if you have trouble.
If you plan on submitting one of the option art or architecture supplements with your application (remember to read the instructions for those!), you may find the Common App to be the easier system to use. The Common App seamlessly works with SlideRoom, the website where those supplements are submitted.
