Software to correct grammar/spelling?

[Tyorik]

alright, so i have to use my ppc-6800 for a little bit as a computer replacement since im far from home and just sold my laptop. that said, i have to type a LOT with it; both through email, AIM, and maybe here. that said, is there anything i can use that will correct things like capitilization and minor spelling errors due to large thumbs. typing on this thing constantly isnt necessarily easy, let alone going back all the time to correct mistakes.

thanks!
