Hi, I don't know where to post this, but I really just want to suggest that some sort of warning is given before a MediaWiki.org user leaves this page. I had recently written quite much in this box, when I decided that I wanted to go back to the previous outcast of the post, before I had pressed "Show preview" the last time, so I clicked "Go back one page" in my web browser. This trick works in Wikipedia, and despite the dialog box that asks you if you really want to leave the page you can safely go forth and back between the different version of the post without loosing any information (I'm using FireFox, maybe this doesn't work with other web browsers). Here on the other hand, I didn't get back to my previous version of the post. I didn't even get a warning, but was brought right back to the page before I had even started to write my post, and when I clicked forward again, my post was gone. I therefore suggest that some kind of warning is given to the user before he/she tries to leave a started post.
