We did test out sending an email once a week when the lessons would go up. Soon I will turn on the ability to send a direct notification to the groups. But I will probably go with the email option because most members who are frequent know that a new lesson is uploaded every Wednesday.
In regards to the AMA notifications. This is done twice a week and a very small amount of members submit questions. I don’t want to spam all members else with notifications and/or emails about it since most members don’t use it.
But I will look for some way to notify just the people who submit questions.
