How to post an annotated game?

Hi,

I pasted the PGN from a recent game into the game editor.  I inserted some comments after some moves.  Then I clicked the "Post to Chess.com" button.  Then I pasted it into a new post in the Games Analysis function.  Something went wrong.  (See the post here, it's just the graphic placeholder: http://www.chess.com/forum/view/game-analysis/caro-kann-without-a-plan )

Can someone tell me how to post an annotated game using the game editor on this site?  Thanks.

[edit] I think there is some issue if ou take too long to post, I've seen a lot of people complaining that they hace lost a lot of work.

Apparently the trick is to preview and save often

Very helpful. Thanks. I was starting with them game editor and then trying to create a post.  Looks like I should start with a post and then edit the game from there.  I will give it a shot. Thanks again.
