In that case, it wouldn't hurt to run everything by a spellchecker once you're done writing it, just in case! It's a perfectly reasonable mistake though - lots of people just wanna get the ideas out ASAP, before they lose their train of thought or something, so you end up with a lot of errors.

I'd also recommend rereading what you've written before posting it, with or without spellchecker. I mean, if you intend for others to read and enjoy your story, it's a good idea to read it over more than once to yourself. It's also a good way to catch other errors, like if your pacing is off or something doesn't make sense.
