Did a search of "spelling checkers", and didn't see anything listed. So I thought these links might be handy for some people. Handy plugins for anyone who uses forums.

Theres also a universal application, that does spell checking as you type.
It works in all web browsers: IE, FireFox, Opera, NetCaptor etc.
