Upon login, you would be able to see the marketplace dashboard and just at the top right corner of the dashboard, you can click on your email. It will show a drop-down box (trade, wallet, profile and message centre). You need to click on profile so you can complete your profile (else you wouldn't be able to conduct any trade on the platform).
When you click profile, it will take you to the dashboard below. The next thing to do is to click on profile and select either (individual member or business member), then you fill the boxes with your data.
In the remaining part of the Profile page, you need to ensure to upload the required documents and click save. Then you have completed the first part of your profile.
