Speaking of drafts, it just so happens that last night I had a dream about making a RP post on here. The server disconnected, but I was relieved to find it was still there when the page reloaded. I saw this grey message box with black text and border saying something like "Reloading your post...". Coincidence? Is the intention to have a floating grey message box? Because if so... like wow.
It's not implemented on the server yet. Not sure what you saw.
However, the browser is often good about remembering text form data. For instance, I clicked a link while writing this post, clicked the Back button, and my unfinished post was still sitting here. So if you ever land on an error page or if your internet is down when you submit, you have a good chance of recovering your post by navigating back.
