Hey, October kid, my birthday is right in the middle of October;)
By the way, I never learned any grammar rules, and I don't make mistakes^__^
I've been reading since I was three, so I guess spelling just got ingrained in my brain:(
And about spelling - it's all that same intuition, the name of which I can't remember! I have it too, although I only get a four on dictation (trust me, there are words where intuition doesn't work, but there aren't that many of them).
Where do we end up when we save the world?
