I recently have been having some difficulties with my usual email address (john at jmaier.net). In light of that, I’m using my Gmail address as my main address until those issues can be resolved. So please send all emails to: jmaier833 at gmail.com Relatedly, if you have sent me an email in the last 6-12 months and for some reason I haven’t gotten back to you, it’s possible that I simply never got your email. So try resending it to jmaier833 at gmail.com. Thanks!
Update (May 4, 2020): This issue is now resolved. Please send all emails to: john at jmaier.net. As noted above, if you happened to have not heard back from me at some point in 2019, try resending your email. Thanks!
