I have a suggestion that The company Envato issue business card for each exclusive sellers in the company and be include and holds details as they appear in its profile page of buyer as well as bearing the logo of the company.
It can print a business card from profile page in a secure and confidential and can not be anyone else doing the same process only the seller.
As well as the proposed signing of the same design detail above can be used in emails and website of buyer.
The proposal above is useful in increasing the deployment of the company and the seller and thus leads to increased sales and financial benefits for all.
