Is it possible to close our account and erase all traces in this forum

All is in the title . Can you tell me how?
best regards

Can any of us erase our past actions, however much we may regret them?
That said, if you simply stop posting, your visibility will quickly fade into obscurity. Turn off notifications and you won’t even be bothered by people responding to your earlier comments.

I don’t think individual users can delete their account and all their posts, but I believe it’s something that the forum administrators can do.
