If you sign up for this tier you're on the honor system.  What that means is:

1.  You're an undergraduate student (PhDs should pay because if my work goes into your work, it stays with your institution from now until the end of time).

2.  You're around the poverty line and don't have a support system like family money to bail you out.

Do the right thing.  And if your situation changes, move up to the next tier and leave this spot open for someone else.  Many thanks for your support :D

I've been thinking about launching a newsletter for some time.  Newsletter will cover what I'm finding interesting on the internet from a variety of free sources.  It will challenge you to do better in every way.  Sometimes it will include pieces that I've shared on Instagram or in other spaces, but the newsletter collates them into one shared space so you can read them at your leisure.  I share a lot and between Facebook, Twitter and Instagram, you can't see it all.  But with the newsletter, it's all right there.
