Yes, however, the admins only allow ONE name change per user. So, choose wisely since you will not be able to change it again. You can contact the admins here and request it, just include what you want to change your name to and they will do it. www.girlsaskguy.com/contact
I don't think so. You might be able to ask support to change your name, but I wouldn't get your hopes up. It's a pretty easy thing to actually do for them, but nobody usually allows it for some reason.
