There are several tabs along the top of your job box. The "view" tab (1) will show you a summary page with your job's specifications and status. The "edit" tab (2) will allow you to re-edit the specifications for your job. (The edit tab will disappear after you have approved the price.) The "attached files" tab (3) will show you the job's estimate and proof, when they've been generated, as well as any support files you've uploaded.

Below and to the right of the job box tabs are a link for uploading support files for your job (4), and the job's status menu (5). The status menu displays the current status of your job, and allows you to approve the job estimate and proof.
