I don't mind being called by new username. I like it that much. Otherwise, Emily. I'm dropping 'Emma', because that's the nickname my ex gave me because she already had a best friend from her hometown called Emily and I guess that would confuse her? (it would confuse her even more now, because that Emily played oboe, and now so do I. xD) ...But she's my ex, so back to my actual name it is!
Now I have to tell my IRL friends that, who really stuck with 'Emma'... They'll understand, I'm sure. Some just call me 'Em', anyway.
