The Partner Dashboard is where you can see everything that Toxnot users have submitted to you for approval, as well as who submitted it.
When you log on in your Partner Team Account, there will be an option at the top of the sidebar on the left labeled "Submission Admin". Clicking on it will get you a list of submissions, like so:
Clicking on the product name for the submission will take you to a preview of the data included in the submission.
Any number of submissions can be selected and either deleted or accepted. Accepted submissions are copied into your library, where you can do further analysis. You will have full editing access to the submitted products, and the submitted materials will be added to your library as well. From there, you can edit products and materials as any Toxnot user would.
