one can use word
one can use office
you can even use open office
I had found an app that I had added to either IE google. it auto checks everything I type and high lights every mispelled word
Oh by the way, drill down a bit you will see post,preview, SPELLCHECK on your post a reply page
I only caped spellcheck cause it is right there you do have to click the button though.
inside the box on the blank part right click up comes spell checker options.Oh that doesn't help sorry
mine I can right click the miss spelled word up comes a box . one of the items is add to dictionary
sorry it took a while
hope this helps
