Hi! and a question!

Hi everyone! I'm Kerrie, i'll be 21 next month and i'm from MA, USA. i have a questionnn.... i wanted to change my e-mail adress on this site. I used to sign up on wedsites then get SOOOO much junk mail that I made a e-mail account just for signing up for things so i dont get spam in my regular e-mail. but i wanted to change it so i get this mail to my regular account so i know when someone has replied to me. can i do that?? or will i just have to make another account and delete this one?? alsoo thinking about changing my user name to the stage name i choose out. thank you!! 😀
