[Event "?"]
[Site "?"]
[Date "????.??.??"]

[White "?"]
[Black "?"]
[Result "1-0"]
1. g4 d5 2. Bg2 Bxg4 3. c4 c6 4. Qb3 b6 5. cxd5 cxd5 6. Bxd5 Nd7 7. Bxf7# 1-0

I don’t know how to and when I tried to all that was on the board was blank space. How to do it successfully?
You'll need to download/copy the PGN and insert that into a new post.

If it's just a question of copying a game from one of my own posts to another, then I can just go into edit mode on the old post, select the game widget, copy, switch to the new post and paste.
That doesn't work if the source is in my completed games list or in someone else's post, of course.

Press the download button. Then copy the PGN or FEN. Close that and come to a forum. Choose 'PGN' or 'FEN' and paste it.
