Have a spell check
Put a spell check in so that I don't have to waste time cutting and pasteing!
Already built in to most browsers or can be done with the installation of a free plug-in.
I find myself relying on spell check as well. That's why I use a web browser that supports spell check. That way I never have to rely on any 'built in' spell checkers. I prefer using Firefox or Chrome (have built in spell check), but this can also be done in IE by installing an extension such as http://www.iespell.com/.
