Again, these are key to having a good fanfic. Neither one should be noticed, because if someone stops and sees your spelling and grammar, it's usually because it's wrong. Andrew Jackson may have said that a person who can spell a word only one way is uncreative, but that doesn't mean a person should spell a word more than one way.

There's no excuse for not using a spellchecker. None. At this point, every program has one built in, and if it doesn't, there's probably a spell check program you can download for it. You should never, ever, ever post a story online that you haven't run through a spellcheck.

There's a reason I'm so uptight about this: because my own spelling is awful. It's flat out terrible. But those mistakes don't show up in the work I publish online, because I take the four freaking minutes it requires to run my story through a spellchecker before I even send it to my beta-readers, let alone before putting it online.

For the love of God, check your spelling. Hey, if you're really motivated, do it with a dictionary—it's more reliable and more often correct. But at least do something.

As for grammar... Okay, I'll give you some leeway here. Not a lot, but some. Bad grammar is less distracting than spelling (have you spellchecked your story yet? No? Go do it, I'll wait. Thank you.) though it can still be quite annoying. So here's just a few pet peeves of mine, and then I'll leave it alone.

Good vs. Well: Believe it or not, if someone asks you how you're doing, and you're having a good day, the correct answer is, "I'm well," and most definitely not, "I'm good."

Me vs. I: You can tell which you're supposed to use by cutting other people out of the sentence. If what you're saying is, "Mush, Blink and (blank) went to Irving Hall for a show," then you'd use I. Why? Because you wouldn't say, "Me went," you'd say, "I went."

Having gotten those out of the way, there are others, but I'll let them slide. I promise not to yell at you for ending sentences with prepositions or splitting infinitives. (In fact, the title of this site is, itself, a split infinitive.) But if there's something glaringly obvious for the grammar section that you think should be here, let me know what I've missed.
