If, when creating a Goal, you saved the Goal as a "draft", you can publish it at anytime by following the steps below:
Step 1: Click into the Goal you want to publish from your "You" page
You'll notice that is says "Draft" on the righthand side.
Step 2: Click "Ready to Publish?"
Step 3: Click "Publish"
As shown in the message above, publishing a Public goal will make it visible to everyone in your organization, and will allow you to begin tracking progress. You can also continue editing the goal (to make it private, add key results, or edit the details).
