If you look at the recent issue N.3, you will see at the bottom a list of all previous authors, so you will have your username there all the time.
As to being featured, these Magazines are a very new initiative and I would like to showcase different authors in every issue. We can see already that this week has brought together people who had not made contact before. That will build all the authors' followers and increase future earnings.
Having said that, anything truly exceptional by established authors may be included :-)
