As a new user, on the header of the forum pages, I see this "get started" box:
However, the "Introduce yourself" link, goes to a forum that is locked/private, or renamed, or deleted.
TBH I'm thankful that this discourse forum isn't subjecting me to one more DM chatbot onboarding for usage. Though it might be helpful to link the "community guidelines", "how to contribute / formatting", or similar contribution-nudge instructions if the pure socialization forum wasn't working for your site management.
