I think the missing feature is having the communities be able to get a beneficiary cut with posts, so that when the community grows, the mod team can also grow and people can get paid a little something for their efforts.

I think this one is a good idea but one could just set the community account as a beneficiary to their posts. Perhaps just making a reminder on a community page through a frontend would work, like a button of confirmation or that the user opted not to have the community have a share on their post reward.

The user could always decline the option but this one just raises awareness that there is an option to support their chosen community to engage in.
