Link to spell checker

[Gus]

Hi all

iv been reading about the spell checker not for free anymore but i looking into just adding a link to http://www.spellcheck.net giving them the option to click on the link cut copy and paste over there, check and paste back. I know it ain't very good but still gives some of the not so clever ppl a hand leased: I know the spell checker option/button is there i just wonder if it could be linked if not can another button be added or just a link.
The option will have to be when starting and repling to a post so
any input or advise welcome

Thanks

Gus
