Hi mg.mikael,
I'll do my best to answer your question.
Putting out 10 issues a year (technically, 10.5, since November is a jumbo issue) has worked well for FSM. We're a pretty small staff (there's just five of us), so this allows us the opportunity to publish special issues, such as the Great Scale Modeling annual and Essential Techniques for the Model Builder, as well as pursue online ventures.
