Having onboard some people to @hypersub recently I've found some people know of it but don't know what it is. This has been my explainer. Anyone got something better or am I missing something? 

Hypersub is great - you give me an address, I input that address into Hypersub which keeps track of addresses 'subscribed'. 

This time-sensitive list means I have one place to keep track of people interested in interacting in whatever story I'm trying to tell. 

So for Window Seat it means I can send art to everyone, randomize give aways and best of all give permissions during games.
