Make an @live.com account at www.hotmail.com (will redirect you to hotmail)
That's what I have on one of my runescape accounts and its not too much of a burden to type in.
if your looking for like advert accs that you wont need to login to again or something i think its like gurilamail or something and it basically makes an email for you fast and you can accept the email when it comes in, it's basically a disposable email
