I see this has been asked multiple times, and there are several answers, most of which seem to be out of date.
I can't seem to find the screens on my profile page that they're referring to (is there more than one profile page?) and links to profile pages are broken.
What's the simplest way to change the email address, and preserve the username, all of the badges and reputations? That's all I want to do.
I don't have any other way of logging in, nor do I wish to (I'd really prefer not to have to create a dummy facebook or twitter account just to use as an intermediate step to changing my email, but if that's the simplest way...)
I know we aren't supposed to express opinions in questions, but it really is perplexing why something this simple has to be made this difficult. I can't imagine any security benefit to this.
