Fellow weirdo here. I started using Thunderbird back when I stopped using (you’re not going to believe this) Eudora. I _loved _Eudora. it did everything I needed. TB’s been great for years, occasionally less than great but still pretty damn good. It’s like a progressive rock band that changes but still feels a bit familiar. Like Rush. Okay, Thunderbird is Rush. No wonder it’s so great. See? This is why we have the internet.
