You do NOT have to put your actual Real Name, just what you like to be called is fine. I don't even think that information is saved anywhere. I can't find a section for it in the user settings at all and have never heard of anyone mentioning Aywas requiring their name, needing it changed, or any other reference to it at all. I was actually a little surprised to read your post! That's how little the "real" name bit matters. My guess is that its just for the application bit.
