I completed the certification exam today and tried to publish my profile.  After I uploaded my government ID, I got an email saying I need to submit one of the following (none of which I have, since I am a sole proprietor with no formal business entity yet):  

Please submit a Notarized Copy of one or more of the following documents

• Articles of Incorporation
• Business License
• Corporation Bylaws
• Shareholders Agreement
• Certificate of Limited Liability Partnership or Limited Partnership
• CPA License Information / Proof License is in Good Standing

Nowhere on the site does it specify that we need to be incorporated, licensed, etc to join the program.  I would not have wasted my time doing the training if I'd known this.  Can someone explain why the above is necessary?
