The Webmasters have been requested to look into this problem. I am not tech-savvy at all, but on quite a few occasions when I have typed out something, closed the tab and realized that the content was not there when checking back, I hit Ctrl+Shift+T and found that the page on which I had typed the content opened and the text was intact! I did it just now also, with this thread. One thing you should not do is press the back button as this I think makes the earlier typed data vanish.
Another thing that I wisely learned in the early years of doing online work is to hit the Ctrl+C keys, whether it is a short answer in the forum or some additional text that I added to an article after submission, then Ctrl+V on to a Word doc. So make it a point to do this hereon, especially if it is a good length AE answer or a Forum response.
Also, in the case of an article, I have this habit of quickly saving it in a Google doc in my email. That way, in the remote chance I do not have time to right away submit my article and when I come online again my laptop had stopped functioning, at least my effort is not wasted.
