It used to be 10 quality posts. The forum still can hold 10 quality posts but now you are limited to 7. That should be all you need to get the job done.
What we actually need is a limit on the number of quality posts you can post - imagine the devastation you could create if you were able to create so may posts!!??
Look, if you can't make your point in just one, maybe two posts... well, maybe you shouldn't be posting... at all.
No more than 10 quality posts should be allowed - at which point, you'll just have to register on another forum and try to keep it to just 10 posts there.
It looks like Colorado is working on a 15 post limit - making them one of the friendlier states.
