I know this is an old thread now and decisions might have been made but I would like to ask why not give people the choice? People in the "It's not a game crowd", well to a lot of people it is... it's not real life and I feel that kind of thinking is what has pushed people away from other platforms similar to POSCON. Is there any harm in giving people the option to choose whether to display their name or a pseudo name?
At a minimum people should be made aware during sign up that the name they put will be visible - that way they can make something up if they aren't comfortable using a real name. I'd still advocate for full freedom on username, without them being offensive of course.
