If any user want to delete their account, they have to contact the corresponding forum administrator. For HKBF, please use your registered email and send an email to info[at]hkbf.org. Since HKBF and HKBRDA are sharing user account. Deleting the account would remove all the permission actually. Therefore, if they want to maintain access to either forum, they could only apply for removing all permission from that forum.
