Which Serenity character are you? I give this quiz a 7.5 on the DavesBrain's BlogThing Scale. That's 3 spelling mistakes over 40 questions.
2 = 1 spelling mistake for every 50 questions/sentences (pretty good)
10 = 1 spelling mistake for every 10 questions/sentences (crappy)
20 = 1 spelling mistake for every 5 questions/sentences (atrocious)
