The best way to contact me is to email christopher@letterd.org
I prefer to use Signal, Matrix, or Deltachat for messaging. I could also connect with Telegram, Sessions, SimpleX, or XMPP. If your are not signed up on one of these avenues, I’ll reply to your email with an invitation link. Learn more on this post.
If you are looking for me on social media, you can follow me in the Fediverse. I do not post all things publicly, so it is best to create an account on a Fediverse server or email me for an invitation to join my server. If you don’t know what this is, just ask me.
