Change Job Name
You can easily change the name of your job, as long as it hasn't been mailed out.
On the job list page (click "My Jobs" in the top navigation bar to make sure you're on this page), click the word EDIT to the right of the job that you want to modify. In the pop-up menu select Change Job Name.
Keep in mind that the job name gets locked once we've mailed it, so be sure to update it prior to it getting mailed.
