After a few of the same questions flowing in, I've written up this step-by-step guide to help you get started.
Step 1: Create Patreon account.
1. Go here: https://www.patreon.com/signup
2. Click Sign up with Facebook or use your email to sign up
3. Receive confirmation email in your email inbox from Patreon.com titled Subject: Patreon Email Confirmation
4. Click Confirm Email button
Step 2: Support the "Epistolary Club" Level
1. Go here: https://www.patreon.com/eliotmichl
2. Select Epistolary Club
3. You'll know it worked when you see Patreon display my Thank you message. In addition to a letter every month, you'll also receive updates about my work and Patron-only poetry.
