Another update; Added a feature to the "Top Speed" page where you can press a button to open a text version of all the values in the form. Then, you can copy/paste it in a forum post.
Just go to the "Top Speed Estimator" page, enter your values, calculate the results, and then press the "Export Text" button to open a help window with the forum values in it. Pretty simple.
I may add it to the other calculator pages if people seem to like it.
