So I'm letting my previous two "test" posts stand for posterity, because that is just how I roll. I added a protected area for management and a very basic insert script. (I do mean basic. I'm staring at it now, and it's nothing but a bunch of unformatted form fields. I should be grateful that I bothered to put in labels.)
But I digress. As you can see, it handles line breaks and Japanese properly, and that's about all I need it to do for now. I just wanted something I could easily use to post from Tokyo.
