I have a program for students that releases content but then after a period of time (say, 2 days), makes the content unavailable again. Essentially, it is drip released and then locked again. This increases engagement exponentially because of the "fear of missing out". I used to have this run via my wordpress site with a PHP/MySQL database, but that became outdated and I could no longer update the PHP without $$$$$$. I did find a content service provider that allows me to release then lock content but I don't like their design features. After a long search, they are the only provider of such a service. It allows me to not only deliver this particular program but also to run, say, short 5 or 7 day challenges, make them unavailable at the end, and then re-run them again without having to re-upload the content. It works soooo well. This UX is of course doable by MANUALLY locking content or changing its URL, but that is a real pain. Making it doable simply by date and an on/off switch makes it amazing!
