(Its a bit off-topic, i know - but because below have helped me much then posting at Apolyton, i just thought that i should mention it).
Not all Apolyton visitors have english as their native language. Heres some help along the way:
Spell-checker software (Babylon, higly awarded):
http://www.babylon.com/newsite/index.html
Spell-HELPER (not the same thing as -checker):
http://aspell.sourceforge.net/suggest/
(With spell-helper, its enough that you type how the word *sounds* like, and you get lots of relevant results).
I use above, and it helps me a great deal.
