hm. i can only think of bad coming from this, sorry to say....
1. Primidea will take NPM over if they do accept it. they will add a few more editors, if not replace them.
2. its really hard to come up with projects for that many people to be interested in, every month, and still fill a mag. if anything, it will stress the hell out of everyone to just reach the deadline.
3. Primedia doesnt have to accept it, but, they can now start their own research and development team, and start their own Nissan mag, now knowing there is a demand for such an item. im sure they have many more contacts than imaginable in the automotive world, so this really wouldnt be a problem.
4.lots, and lots, of new people on the forums(which isnt really bad, but the amout will most likely be overwhelming to the current moderators). also, many, many people not using the search button

.
the good side....
1. NPM and NF.com will be sponsored, and the writers and maybe even the mods will recieve income. no more worrying about not enough contributor accounts to pay for site hosting

.
2.if there is enough interest in the physical mag, and it sells, Primedia could(big could) help with payment of new projects/car buildups. but doing this kinda makes it their property, etc etc etc.
3. WOOO HOO, i finally get to read about nissan 24/7
4. parts makers will finally start making more availible upgrades to a demanding crowd, much better than going "ok starting a GB on cf (insert part here), but we need 50 people to sign up and prepay........".
these are my $0.16 cents, take them as you will, but nomatter what, it will be a step forward to the community.
