Rafi Zimer

Hello Dear Friends. My younger brother gave me the avatar. Is it possible to change details? For example avatar's name, birth date, etc? I am interested into become a SL member and I do not want to create new avatar and buy everything again. It gonna be so huge expenditure If I will have to buy everything again (the same things as I have on my brother's avatar). I have been playing some time as Rafi but I am feeling bad with sensation that everybody are thinking that they are talking with Rafi (my brother) , not with me. It would be so great to have possibility to change avatar's name and account details (my birth date, etc.). I am waiting for your answers. Greetings!
