Don’t know till you say so, hence why I asked for specificity 
. Unfortunately your forum account can’t be delete. As from the Admin panel:
Users can’t be deleted if they have posts. Delete all posts before trying to delete a user. (Posts older than 60 days old can’t be deleted.)
Can’t delete all posts. Some posts are older than 60 days old. (The delete_user_max_post_age setting.)
I am sorry about that but that’s how the forum software Discourse handles this sort of thing. Your account can be deactivated though. Feel free to send a DM to admins if you’d like to do that sort of thing rather than a public forum post.
