Looks cool. With it being in "private alpha", if I drop it in a Slack for an open source project with which I am involved, and the maintainer/leader wants to try it, will he be able to sign up?
Good question, and yes! I'll get a text message as soon as they ask to sign up and I'll have them in the alpha by the end of the day. Anyone who is already in the alpha can invite unlimited teammates.
It's probably ready for public beta ...
