Most of the AF-writers can't write english good enough for a publication (some may say thats also true for some of them when it comes to german :-D ), so you would need a completle new staff.
Most ads in the AF are only of interest to german/austrian readers, so again new one needed.
It would offcourse also mean printing 2 different magazines.
Basicly you would end up with a whole new mag, only sharing name and small parts of the contents, but I'm sure Andreas would be ready to talk if someone would want to create an english print-mag.
