Hi folks!
Those of you who have been with me on the Send Later journey for a Very Long Time might recall that long ago it used to be possible for me to upload beta releases of Send Later to addons.mozilla.org (AMO), and users could choose to subscribe to the beta channel to get those releases instead of just getting production releases. At some point AMO (and subsequently addons.thunderbird.net) got rid of the beta channel functionality, and that has made it more difficult for me to recruit and retain a group of people willing to help make the add-on better by testing beta releases.
Well, I'm pleased to report that the beta channel is back. If you're willing to get beta releases early and help me find bugs before the whole user base sees them (and I'd really appreciate it!), here's how to join the beta channel:
You can switch back to the main release channel at any time by repeating the steps above but downloading and installing "send_later.xpi" instead of "send_later_beta.xpi", or by installing the current version downloaded from addons.thunderbird.net.
Thanks for your help making Send Later better!
