Once you have logged into DSLabs with your login info you should be able to scroll down to the section titled "Supplier Sourcing Training" and click on "Supplier Directory". Once in there click on "Go To The Directory" and this will take you to DSMOZ.com. There you should be able to login with your DSLabs username and password and access the supplier directory.
This should work, but if it doesn't please email us at email@example.com and we will look into it further. Thanks =)
