A bit of a meta suggestion:
Maybe mention in the public DayOne thread that the Early Access phase has begun for Patrons. The benefit would be two-fold I think. One, it would help stoke interest a bit. And two, it might also nudge some people over the edge to become Patrons.
The potential downside is obviously that dayone.xboxera.com isn’t a particularly hard URL to guess, so you might end up with more testers than you had in mind.
