I believe the best sources for new players are the wargamers.
I think about the best painters here : There is a website where you can show your work, it's called "coolminiornot"'.

I posted my first figure (49ers center) on it, to promote the hobby (not my skills, because I know I'm just a "tabletop level" painter).
I'm happy I didn't be "flamed" by the visitors, since the level is very high on this website.
I can't believe that most of wargamers just don't know this game ! In USA since electric football is a classic child toy for a lot of people between 30 and 60 years old, most of US wargamers should know at least the concept. Whit all the skilled painters and modellers in the wargame world (not speaking of casters and other minis companies), it could bring a great new blood to MF.
In france, I suscribed to the biggest wargame forum too. I made articles to show everyone this game. Actually, one person bought a game and figures, and I believe, suscribed here too. Not so bad for France where US football is almost unknown.
I also tried to promote on NFL or real football french dedicated forums, I just found a polite success for now. People interested in football here seems to not be interested in modelling. I don't know how it is in USA, but usually here in France modellers, wargamers and other hobby people are not the same than the people interested in real sports.
