Thanks for writing. It sounds like you are confusing AdobePortfolio with Adobe Stock. To sell your stock content you must create a contributor account at contributor.stock.adobe.com
Thank you for thoughtful answer. However I uploaded my contents on adobestock, the website you linked. There are both portfolio and sale part. And I have my account with my email already. Is there anything that I don't know? Sorry for being bothersome, but I really want to register my content on adobestock.
If the images images are approved and in your portfolio at Adobe Stock, that means they are available for sale to Adobe Stock customers.
Thanks! You are so kind:D
