Which messages are currently being sent? What exactly is “default”? When I registered here in 2021, after registering, I received a message from Discobot explaining the trust levels and offering a tutorial. Then I received the TL1 and TL2 messages
And the invitation for the advanced user tutorial.
But on my forum the first message from Discobot which explains trust levels and what is needed to get rid of those limitations is no longer sent because a Discourse update about a month ago silently disabled the Disable Discourse Narrative Bot welcome post without telling me.
Since you say you rely on default messages that are sent when members join which message do you mean? Discobot seems no longer to be default.
