I want to delete a post or maybe several posts that I have made in the past, or otherwise change my "screen name" because I probably should have picked something a little more incognito. Either way, I can't find a way to do either of these things and I, as a fairly intelligent person, have been looking around the site for an hour. So, if it is not possible to change my name and have it changed on my past posts as well OR have the option to delete some of my past posts, can someone let me know? If that is the case, then I just want to delete my PF account and hopefully this will delete all past activity... but I can't figure out how to do that either. So, any help would be appreciated.
