I just found out that a minyan friend is teaching a class on a free online Jewish learning site called OneShul. I haven't watched any of the videos myself, but I have heard many d'vrei Torah from this friend and I'm sure his will be a great class.
Appropriate for Shavuot since the book of Ruth is traditionally read on the second day of Shavuot (maybe on the only day of Shavuot in Israel?). Of interest to converts since Ruth is considered to be the prototypical convert to Judaism.
My friend is giving a class on Jewish death and burial practices on Tuesday, May 29 at 8pm (Eastern time). I assume it will be available to be seen online at any time after that as well.
