Thanks for coming back Cristián. I see that Jason and Raam jumped ship because they could get good jobs at Automattic. I suggest that one reason this could happen was that S2Member has such a poor business model and does not charge for support - hence they had no incentive to stay. I hope they passed the last year’s income over to you otherwise its means that you have the cost of supporting all the existing members but none of the revenue. Not fair on you I think.
I am sure that many users would welcome the peace of mind that would come from you changing the business model to annual support. You just have to look at MemberPress (https://memberpress.com/plans/pricing/) to see how wrongly priced S2Member is. Unless you fix the business model this will probably just happen again.
While you were away Krum did a good job of keeping S2Member alive. You might want to chat about to him about a joint effort to publish a roadmap which would be the first step to restoring momentum.
Thanks again for your effort.
James
