Remember - I learned this from ChargewithSword when he taught me how to write - when you type on the computer, always print it out and proofread from there. Our minds are trained to skip words on the computer cause we're used to short messages, but we read normal on paper. Just so you know.
And don't worry about your writing, you are far from the worst writer here. I can't say who the worst writer is on a VM though.
