I could see where taking a class of this sort would be kinda difficult online. I'm kinda lucky that when I took my linguistics/grammatical courses, I had two totally awesome teachers who helped me a bunch. Otherwise, with my dyslexia, I probably would've had problems, too.

But I have total confidence in you! I think grammar courses are kinda fun, once you get into the nitty and the gritty. But, then, I'm weird. ^^;
