I learned in typing class to put two spaces after a period, but I've gotten out of the habit. I think my grammar is tolerable, and my spelling is excellent. I cringe when I see mispellings, but, different people have different strengths and weaknesses, and one persons weakness shouldn't be used to make another person feel all high and mighty because it is one of their strengths. Being good at english does not make you smarter than someone who is not.
I suck at math. I tested into slightly above retard math in college, and I've noticed that many people that are great in math are horrible spellers. Y'know how it seems people are either better at math OR english? I don't think they are better than me or below me, just different. Shit, I'm actually quite jealous of anyone that looks at numbers and doesn't get a pit in their stomach.
I think that as long as you try your best to make things readable to others...you are doing good. Reread your posts...see if you can follow your own words and make any sense of it. Use punctuation and spacing and even different paragraphs. It will make the anal control freaks happy, and then the rest of us
don't have to fucking hear it.
