This not really a bug, I would like to know if it is possible to use mattermost on Thunderbird as client?
I don't find information about this feature, but I saw thunderbird in the list of clients.
Thunderbird is listed as an email client, as in you can use it to receive email sent by the system. As far as I know, there is no way to use Thunderbird as a UI for Mattermost.
Ok thanks!
