This is actually a hit-or-miss situation. There's a sliver of a chance that an affiliate under your belt will come back after going AWOL for months. However, don't bet on it...
It's good to send supportive emails to your team. But don't be discouraged if they fall on deaf ears. If they refuse to respond or log in, that means they don't want to be financially independent. Just focus on the affiliates who do want to take action.
