Is there no way to delete my account here?
I have searched in settings and cannot find it.
Searching outside the forum would seem to be the solution here - according to the Discourse Meta:
So basically for a user to delete account: Three days or less old and you have 1 or less post. Said user must go into their preferences and scroll down to the bottom where there is a unmissable red button saying Delete my account.
If your account is over 3 days old, or has more than 1 post:
Users who want to cancel their accounts can reach out by email to the site owners… …Then the admin can remove or anonymize them.
