Usability tests are updated in order to pay more attention to free and paid membership. Also, the support page tells the difference between these memberships to help the users learn about them more clearly.

Quesions 1-3 are quite easy, regardless of following the navigation bar or the main page. It should be noted that some features are not achieved yet, such as adding goods to the cart or limiting the articles to certain users. Therefore, question 4 and 5 are tested by the users with my explanation. Question 4 is not a good question. As for question 5, the lesson learnt is that I should find the better way to differentiate between different kinds of articles, which are the guides part. They are not organized well. Maybe I should add some icons, which could be more attractive.

What's more, I should really speed up to finish the project. Three parts should be focused on. First is the backend functions like logging in, second is my intended features like 3D models, and the third one is to manage the visual elements in a more user-friendly manner. I paid too much attention to the first two, which are the function part. More contact must to made with the users.
