Jake, you are asking that everyone who has ever posted a problem on this forum - including those folks who have passed on to their eternal reward - come back and re-post everything. That puts an unnecessary burden on us, both living and dead. Instead, why don't you go back through all the posts and make a tally of each discreet problem? Then you can draw a nice graph. We will all be mildly interested in the graph when it's published and we will thank you for your effort. Or maybe you need a less cumbersome project for your statistics course.
