YS> set up an awful phone conferencing system after a few weeks
I don’t think we should fault anyone for doing something wrong: this was an unprecedented situation. As long as they honestly tried, and then changed something based on feedback. As it says – if you see a Talmid Chacham sinning at night, do not reprimand him in the morning, as he surely did teshuva. That is, a person can be a T’Ch without being perfect, but being able to do teshuva is a requirement.
