I would like to delete my account. I checked the help section, which instructed me to go to my profile and click on 'Delete Account' under the "actions" section on the left. However, I am unable to locate both the "actions" and the "delete account" link
I don't think I've heard that there's ever an option in the profile section that allows users to delete their accounts, because for what I know, there's none. You can delete your bitcointalk account.
I really dont know what your reasons are for wishing to delete your bitcointalk account but you can't, so the best you can do for yourself is to change your email, I believe you can do that one, so go ahead and change your email and abandon the account.
