SUNUVAB...!
I hate when I make long posts then check everything, and click submit and then ... NOTHING! BLANK PAGE!
And of course you can't hit back, because if you do there is nothing there, if you hit refresh it's still a blank page!!!
I'm sooo pissed!!! WTF!!!
I usually do a select all and copy before I submit posts, just in case something like that happens but it never fails when I do forget to ctrl+A then copy, I lose the post!!!
Okay I thought venting over here would be more appropiate than in the Weight Loss Support. So now I'm going back over there and try again!!!!

It won't help this time, but if it happens again maybe this will help. If you go 'back' and the field is blank, right click in it and you'll get a popup menu. Choose 'undo' and it should paste everything back in.
