I have accounts on several Stack Exchange sites. I do not wish to be removed from all of them, just one or two that I never really use and am no longer interested in. Is this possible? If so, how? If not, please consider this a feature request.
You can delete your own account in two ways:
All profile deletions are per-site, so you can leave an individual community without affecting the others. If you are on a lot of Stack Exchange sites and want to leave them all at once, the most expedient way to do so is to email the team and request network-wide deletion by going to the "contact us" page, choosing "Other" from the list of topics, and explaining your request/situation.
