I opted not to edit the Language file as I use a separate Who's On Line island which I prefer. Unless there is any other reason to edit the language file other than the "key" output in the Members On Line island then I am good to go. It seems to be fully functional and I love how this makes my chat room and my PhotoPost integrations look absolutely seamless. (Yes, I did this for my PhotoPost as well.)
To be honest, I'm kinda giddy about this!
