I have yet to hear anything from ACLS. I am assuming that the others are right about the situation. Seems like a slower roll out for preliminary acceptances/rejections.
Still no news. But I looked at past data so it could literally be any time this week in addition to multiple waves of acceptances/rejections. It seems people think today may be the day. Best of luck everyone! Be kind to yourself like posters on this say: https://academicjobs.fandom.com/wiki/Dissertation_Fellowships_2022-2023#ACLS_.2F_Mellon_Dissertation_Completion_Fellowships
