I've lost quite a few posts during the last 11 years. It's easy to do. When I lost a long one, I was not a happy camper. For awhile, I wrote them in Word and then pasted them onto the forum. That worked, of course, but that habit slowly slipped away. On some forums I'm on, a tiny barely noticeable message flashes on every 15, or so, seconds, in the bottom right corner, saying it has saved what you have written. Nice feature.
