Consider the relationship status event. In that way, we avoid putting stuff on mega lists again :) https://github.com/vitorpamplona/nips/blob/relationship-status/81.md
Is this for engagements? I DO!
You can add people to lists by adding an `n` tag with the name of the list. It flips the data structure around. On the UI, just offer filter by `n` tag names and we are done.
No more race conditions.
