I tried following the facebook login guide posted quite a while ago to connect my facebook account and my account on here, and ended up making a new profile, the one I'm using now. I wanted to try it again, but I would need to delete this account to do that, I tried using the search for how to delete an account using the search and I got just a lot of threads asking for bans. I was wondering, could someone tell me how to accurately connect an existing profile and a facebook profile on here, and also, could someone tell me how to delete my own account (I'd ask for a ban but I figure that would just put me in a ban list and not actually help me with the issue). Thanks
