No, I do not share the MPP. And, my members are cool with that. Here's why: I am the sole administrator for the Facebook writers forum group; I am the sole editor and graphic designer and publisher for the ezine, and, I am the sole administrator of the publication here on Medium. When I transitioned the ezine to my profile (from the WE PAW non-member profile) after becoming a member/partner, I asked my members if they were okay with me publsing their contributions and the ezine on my profile where I would earn on them. No one dissented.
The majority of the writings on my profile are my own since 2016. The ezines constitute a small percentage of the total. For all my work for myself combined with my work for the group ezine, I earn less than $30 a month. There is no one in my writers forum who begrudges me that meagre pittance for all my work.
