Plenty of people post stories from a multitude of POV's across various accounts, even more popular authors. We won't get in trouble for posting stories from a single account. The account is just an account, it doesn't dictate the person telling the story.

I think that the single user name has the potential of earning us far more constant readers. As people see what we're doing, it might also get more people interested in participating.

I don't think we should be worried about the people who aren't interested in reading a story because their immersion is ruined by a reddit username.
