Ok speaking from experience and only trying to help you guys and get this place off the ground, remove the 25 posts you have in place.
I came here to share and I know Wolfgar the same, when you've got members posting here each day and the place is active and you've got a few thousand members then sure you can set those kind of rules but when your tyring to get the place off the ground you want as much activity and sharing as possible, we both render.
You could count on one hand gfx sites that are still active today,a couple I've come across are on the same boat as you, maybe 40 members only though there is more activity as they don't have this restriction in place but its still a struggle , times change and you need to move with them.
What harm will it do you?
Would you gain something?
I don't cnc and im not a spammer, just looking to share as i do on other boards.
