I got an email telling me to fill out my report, but I already answered the questions on the action page

There are two different places to give feedback when participating in a sampling or party action, the challenges and the report.  The challenges are optional to complete.

Your report is further down, and can only be unlocked by checking in your package and verifying that you have sampled the product or hosted your party. It will consist of a series of multiple choice or open-ended questions and include steps to upload additional photos and a link to your blog post (if you wrote one). 

Remember, your report is not 100% complete until it tells you that it's pending moderation!
