Shim, I think it would have to be up to you to make sure the spelling is on par. If you are volunteering to be a writer, you have to be a proofer as well. That's how it works in the professional writing world. Yeah, writers have editors, but those editors are paid. So unless you are willing to pay someone...

What Jay is looking for is a very professional site that will attract lots of people including sponsors. If we have a site laden with typographical and grammatical errors, why would they want to advertise on us or for us? We have to each be our own system of checks and balances. Besides, automated spell checkers only find words that are spelled incorrectly. There are other ways to make typos. You could have a properly spelled word in the wrong place or being used incorrectly. Spell checkers will not catch that.
