There are a couple ways one can go about spell-checking their story. The options are:
Go to this on-line dictionary and look the unknown spellings up on your own.
Cut-and-paste your story here, and it will be spell-checked within a day or so (Real Life permitting).
Upload a file from your computer here, and it will also be spell-checked ASAP.
Ask one of these nice people to help you out (sorry, there aren't that many right now...).
That's it, for now. Suggestions should be sent my way.
