Well, right now minipainters is a small site/forum of general orientation-as it is it will suffer quite some struggle to grow-I think you could specialize on a certain topic/side of the hobby, otherwise most peaople will simply stay on CMON, since it\'s bigger, has more members to chat with and has a far bigger gallery.
Just an example: turn it into the ultimate NMM pinting forum, find some articles and skilled painters from CMON and ask them permission to use their articles and pics possibly convince some of them to openly discuss their minis, the complete procedure they use to paint them and some more little triks, then just exchange the banners with CMON and it could grow preatty fast.
A way to keep the flow costant would be to add every week a new article on a specific model with a slightly differen NMM (you have some with better golds, some with better chrome, and the simple ones for beginners-there are always some little differences and little triks that each painter uses...
Just an idea
