Ill give my perspective, as the owner of or PRESIDENT or ruler, or loser, whatever of NOT SUITABLE FOR GENERAL EXHIBITION.
Basically, at the time, Movie poster talk started deleting, and locking posts, there was a time when to post you submitted and then if approved it would go live. A member Ill call him B made one of the funniest and cleverest post ever to get by the censorship. There was a lot of adverters/sponsors, and some were getting angry that they were being "picked" on, for whatever reason.
Jon I think realised it was a headache and not worth the few bucks he earned.
I called or emailed, cant remember, Phil and we decided to start an alternative, mainly because we felt people should be able to speak freely (and as Holiday says within reason - I have deleted 2 posts in the last few years - apart from Spammers who get the trash), both were particuarly... hmm, well, forget just being racist or sexist, got a little worse.
We also decided that it should be advertising free, and over the years I have had MANY dealers email and ask to advertise, also dealers asking me for special favours regarding what people post about them.
End of the day read the disclaimer at the top of NS4 and then like it or lump it. I make no $ from it. Just like chatting with fellow movie fans.
re NS4g Vs MPF, yeah we snuck in by a breath, shame we didnt "borrow" all the email adresses from MPT (ahh bitchy)
