I submitted applications three times to their waitlist over the last several months, and I haver never heard back with any response at all. I think my use case is very reasonable (integration with https://cocalc.com, where we use ChatGPT's API heavily right now). My experience is that you fill out a web form to request access to the waitlist, and get no feedback at all ever (I just double checked my spam folders as well). Is that what normally happens for people?
