So, it seems we have two more cases on the same thread. On Meta board where there is supposedly more quality.
Why did you want to delete post including your accounts?
To me deleting your account by yourself is a bit difficult because you don't have access to do tha, what you should do is to have those post you don't want deleted or alternatively you leave them to serve as a reference purposes to how you started here. What most don't know is how to keep records on how they started forum from little and became larger.
OP, go to settings, reset your account password, but before you type the new password, kindly close your eye and type in different letters from your keyboard. Open your eyes after then and don't cross-check the letters, then submit it and walk away. That's a way of forgetting about your account if you don't actually want to gain access to it.
Your case with the answer fits right into the topic of people who don’t read posts and don’t read what other people write, but only respond to the first post that the OP creates. If you had paid attention and read a little more, you would have realized that the OP has decided on the issue that concerns him.
The case of SmartGold01 I think is more serious, as he is replying to the thread in meta, without reading what the OP himself has posted in a later comment on the first page, just two comments before.
