I would like to delete my Stack Exchange profile. Can any one tell me how?
As Jonah has pointed out, if you wish to delete your account you need to contact the SE team using the "Contact Us" link, which can also be found below.
What happens next?
Given that you've accrued a reasonable amount of votes for your questions (as well as voting up and down on a number of questions), it's quite likely that your account won't be destroyed, it'll just be deregistered. That means your questions, comments and votes will remain on the site, just under an account not linked to your personal info and no longer under your control.
Reasons for quitting
You seem to be rage-quitting after finding out that copying questions over from moviemistakes verbatim isn't acceptable conduct. This was an honest mistake and something that's quite easily fixed. Don't quit, or, at the very least take a few days to think about it.
For the record, turning these into acceptable questions (by attributing the content) is a very simple process that takes about one minute per question. If you do quit, I'll be working my way through your questions and correcting them.
