Overview
To see commentating in action refer to this page.
Everytime someone playing a game you are commentating on is finished with an entry they will reassign it to you. You will then receive an email at your registered address telling you about it. The email should have a link so that you can immediately begin to add your commentary. Failing that you can login and then click the Entries button in the top left to find the entry in question.
You can type your commentary directly in the middle of their entry. Once its typed in you highlight it with the mouse, and then click the Quote button to the top-right of the Entry Body section. Its the button on the far right.
That automatically wraps your commentary in special tags that make it stand out from the rest of the entry when published. Once done, Save your changes to the entry.
Once the whole game is over you have to set each entry to a Published state by going in to each entry in turn, changing it to Published. You also have to change the category of the entry from the individual players view up to the main game category. Once done save it again.
The game is then viewable on the site for all to see.
