Sorry for the late reply and thank you for the love!! :) Ok, to change your username go to the ACCOUNT tab, then click it, click EDIT SETTINGS, right under the blue tab that says "Send Private Messages" you're going to see a box that says EDIT SETTINGS with an arrow facing down in a small white box, click the arrow, go down to EDIT LOG IN INFO, then click it, the computer is going to redirect you to another page, enter your password. Now, you should see links that say CLICK HERE TO EDIT PASSWORD, USERNAME, EMAIL, etc., Click the link you need, then you should be good to go!! Hope this helps. Let me know if it works for you!!
