Uhhh... yes. I suppose. But no one here will know what to call you if you use any sort of Chinese characters. Go ahead and post whatever assortment of characters you wish to use and I can just copy and paste them in for your name, if that's what you really want.
Oh, sorry. Was away for awhile. You should both be good now. And Sun, someone already had that name actually, so I just changed theirs, but if they request it back... gotta give it back to them. But they likely won't.
