I have been using @thunderbird for the longest time now since I ever needed email. To be honest I've used it when I needed to then left, but something always brought me back to #Thunderbird.
Recently I found out about the #ThunderCast #podcast and it's great to hear from this open source team and the time and energy to keep it modern. Just updated to the #SuperNova 115 version and it's awesome!
The podcast is where I learned Thuderbird has addons too!
