Merit sources can be removed by long time of inactivity, and in this thread, merit source applicants who are inactively in latest months are not included.
Pursuant to the title "waiting list" I suggest you would have included all the merit source application that is awaiting approval from the admin. After cataloging them all you can indicate those users that are not active and those that are active, because if the admin wants to use your list to approve any application, the topic can help them know which applicant is active and the ones that are not active. Apart from the admin, other users on the forum can also know which applicant is active.
