MistressSummer

I made a username called MistressSummer, well what a BIG mistake that was!!!!!!!!!!!!!!!!!!!!!!!! As well as exploring SL, I am looking for a SL partner and everyone has said that with a name like that i am not gonna get a SL partner. So can i change my username to summit like MsSummer, the name atm is giving me trouble i do not need, or if i have to make a new avatar, can linden labs please transfer my inventory as I have stuff I can not transfer and stuff I have paid for!! Thanks x
