Recently stumbled upon 10FastFingers, an online typing test to measure your WPM. You can create an account to keep track of your progress. The basic test is here. Just start typing in the box and get as far as you can in the allotted minute, after which it tabulates your results, and you can click the refresh icon next to the timer to reset if you make too many mistakes to tolerate. So far my fastest is 119 WPM(position 788 of 166433 last 24 hours). If only I could translate that to my actual writing I could knock out scenes in no time at all. So how do you guys compare?
