32 is ad-free because it's sustained by the generosity of its readers in the form of small donations via Patreon! You can pledge as little as $1 per month to read all of the strips, including extra strips that are a bit more personal and aren't shared publicly.
I try to make one special Patreon-only comic every month. Here's a list of them so far!
I'll add them to the list as they're posted!
