anda don't. But anda can use the
link link at the bottom of any page to write to the staff to request to have your account deleted.
If anda intend to open a new account, please make sure to contact the staff first BEFORE anda create a saat account, as multiple accounts from the same IP address can get anda banned (and it is much lebih work to get reinstated after a ban).
It sounds, though, like just not using the site anymore would suffice for you. anda don't need to padam an account for that.
