anyone know a good one that i can add as the back end of my site, at least until it's up. i have to everything via a command prompt right now and it's getting annoying. i'm looking for something like what they use on geocities, just a simple editor. i'd prefer that it's open source and doesn't add anything to my code. something that i can drop into my site like phpMyAdmin ... but for regular text editting.

thanks for any feedback
