As a result of my music career in SL, I have adopted a completely new identiy IRL. There are many people in my life now who only know me as Jed. Even my mom and dad call me Jed now. Many aspects of my life are divided between the Jed identify and my previously existing, real life identity (ie, music & art vs. business & job). There are benefits and drawbacks to this approach which I would be happy to discuss.
You can learn more about me at www.jedluckless.com and I can be reached at email@example.com if you would like to discuss further.
Thanks for your interest in our wonderful world of SL!
