Writing...Grammar, punctuation, and spelling has always come easily to me (Myself? j/k :P) but it's a hard thing for my brother to grasp. I'm pretty good at muddling through posts with less than spectacular grammar/spelling, especially if that person's native language is not English.

(I will not, however, expend any effort on a post that uses tons and tons of internet shorthand, all caps, or lots of l33t. )
