(Continued from here Mark Junk read not working. )
I expect most new posters here come from addons.thunderbird.net where there is a link ‘Forum’ at the bottom of every page. And those pages are localised, which is why some people, quite reasonably, post here in their own language.
There is a sticky here from February 2018 (though I had to use a new device to see it - I must have dismissed it long ago) which says:
"This category is for discussing Thunderbird add-ons/extensions. This is a good place to discuss add-on development, ask questions about creating add-ons, and help others create new extensions.
Below are a few resources you can use to get started making add-ons, or to troubleshoot your existing ones …"
(followed by some links, many out of date).
Despite the emphasis on development in all that it has always been used for questions about ATN itself (or AMO when that hosted TB addons) and individual addons. The eqivalent Firefox group here says “Discussions about add-on development, add-on support and addons.mozilla.org”. This group has no equivalent ‘charter’.
It’s clear that the Topicbox group https://thunderbird.topicbox.com/groups/addons is for development: “… intended for general discussions about creating add-ons, and is for add-on developers who need support in creating their add-ons.”
So the obvious thing is to send developers over there and try to answer other questions here. And the sticky should be updated, and perhaps a charter added to this group. @ryanleesipes
