We have a large goal of Gaggle recruitment in 2018 and think our existing employees can help do this. Would like a way for employees to easily share the invite link with their colleagues. Most importantly, can we create a Gaggle referral program around this. Ideally, we would like to be able to attribute member sign-ups to existing members. Custom invite links for each member so we can track where a sign up came from? We'd then want to reward members for getting more participants signed up.
