I've just spent a long time creating a page that I didn't want to save until it was finished. I didn't want an incomplete page to be e-mailed to group members. Unfortunately when I came to save it, the page had timed out, and I lost it. It was important, but I'm finding it hard to get the motivation to rewrite it!

With hindsight, I could have created it offline, and pasted it into the editor, but I didn't think about it.

Is there any way to get round this? A warning that the page is about to expire would be helpful.
