I would like to reset my profile so I can try again with a fresh record but keep the name that I have. Why isn't this possible ?
Just make a new account and replace the I with a lowercase L, problem solved
That leads to rating inflation across the site. I'd advise against making new accounts for such a reason either, it probably isn't allowed. Besides which, you'd just rack up pretty much the same win record on a new account, so what's the point? If you can better your chess playing, wouldn't it be nicer to see how you improve over time?
