@HoloAndBroke asks
my partner and I collect together. Should we track who owns what, or is that making it too formal?
Jeff answers
I'd agree on what is shared, what is personal, and who can trade or sell each category. It can be a simple note, not a complicated contract. Clear expectations help keep a cheerful shared project cheerful. Don't wait until someone wants to trade the other's favorite to discover different assumptions.
