How do I insert a recent game into a post?

Hi;

I've figured out, I think, how you use the game set-up feature in posts, etc, if you want to start from scratch, but how do you insert a game that you have already played?  That is, how can I copy the move sequence directly into the game set-up feature?  I know it's something to do with the 'save PGN' option, but don't know exactly what...

Thanks if anyone can help. 

This is what I do...

After I finish a game, I get an email saying my game has finished. The email also contains the game in PGN Format. I then copy the entire file and go to "create post". There I go on game setup. There is an option saying use a PGN file. I paste the file in the text box and click next step. And voila! All the moves are shown. To add comments, I click on the individual move and type my comment.

There must be a better way, but I'm too lazy to find it.
