Brandon Sean; Can You tell me ware I can find the page "About Me" so I can fill it in?
If your "Seller Mode" is "ON" you can able to edit the information about yourself as a seller to introduce yourself to potential buyers.
You need to go to Settings>Seller setup> "To be able to change the About me section." to have a quick introduction about yourself and what you offer.
You can click "Manage My Profile" to add more information about your seller profile in the "About the Seller" section.
I hope this information helps.
