cumulative posts

Hi Guys,

Would there by any way to see how many posts were stored in the WP databas e on a certain date.

I’ve been asked to plot cumulative posts on our website vs date to see how fast we’re expanding and see if we’re too slow in adding content, but I haven’t been able to find a way to access historical records of the number of posts on our website. Let me now if anyone has any ideas that might help.
