I just had an entire post that I took 30 mins working on get deleted because I got logged out when I went to post it. I couldn't get any of it back because there isn't any memory of what was typed before hand like there is on GD. Please please please add a way for the post to keep track incase something happens because I don't think I would ever want to work on large posts if I had the off chance to lose all my progess.
I was thinking of draft saving feature already (I have written a modification for this board). I might implement it now, when I see I'm not the only one who'd like it.
Normally when I make larger posts on forums, in general, I tend to do them up in Word or something to that nature. There are even word programs that have BBC code lines pre-isntalled into a drop down menu so you can even preview your post. I usually just use word then copy paste into the forum for previewing though. Might save you some head ache for the time being at least.
