I had a great accidental mistake last week- I was going to reply to a post, when I noticed spell check was avaialable! This was while using Mozilla's Fire Fox as my browser. So far I can't replicate this with Internet Explorer.
Lessons learned: another good reason to use Fire Fox!!
avaialable?????
I find the best way to use spell check is to compose a post on Word, spell check it, and then import it to the forum. I have had more than one opportunity to display my ignorance of spelling (and typing for that matter) by not checking my posts this way.
