First off a big “Vielen Dank” (thank-you in German!) to the folks who helped with the Thunderbird 11 support day.
The next Support Day is the day after TB 12 is released i.e. Wed April 25, 2012. As always, no experience required! Once again, our focus is on Lightning and upgrade from TB 3.1 to the current version of Thunderbird i.e. in this case TB3.1->TB12 upgrade.
