Flux is a network of Creators who can support each other by inviting their communities to follow other Flux Creators.
To join the referral program, select some Flux Creators in the settings and write a short blurb why you recommend your users to follow them for free.
These recommendations will then show up in the Flux flow - just as you are recommended in flows by other Creators. This way, you'll gain new leads without any effort on your part.
