It's been too damn long since we offered something new, so I just implemented spell checking via
Spellchecker.net. It's not as integrated as I'd like it to be, and it has ads that we don't make any money on. But it's damn handy, so I figured, why not give it to people. Since most of the work is done on their servers, it hopefully won't cause a lot of extra processing, but it does require a cgi script on our servers, so we'll have to watch how many resources it's taking.
