ARL I would do 4 times equally spaced over the duration. I get the cynicism, but it not so much for forgetting, but rather so that it reduces the possibility of someone missing the communication, like I did. I missed the mail communication.
While I appreciate your perspectives, my main point is not on the reminder, so I rather not focus further on this. My request is if Nothing can help me redeem now? So, I would appreciate if I can get help on this point.
