Hi Buddy, Welcome to Steemit! There is no way to change your Email Address associated with your Steemit Account, the only email you will ever receive from Steemit is your account opening notification. As soon as you are signed up, which you are 🙂 You basically don't need that email anymore, even if you lost access to that email account it won't matter. Make sure to keep your Steemit Password save, it's like the Private key of your Bitcoin Wallet!
