I understand reasoning for either way on this, but from a coach's perspective, it would be nice if past clients who return to the coach would automatically be classified as a "referral" for the coach - with the coach getting a referral bonus % as if they recruited them. I believe it shows the coach's good work that a past client would want to return to work with them again, and thus should be rewarded. For example, Coach Z works with Client A for 6 months in 2021. Then Client A comes back to Coach.me and signs up to work with Coach Z again in 2024. Coach Z would then get the referral bonus for Client A.
