Hello: I have had my Mturk account for many years. I used it for the first 2 years or so then I forgot all about it because, being outside the US, I wasn't able to get paid other than giftcards. This is not the case now. So I am back. Long story short, I am learning about a few places (such as this) for reviews, etc, and I am slowly learning to use them. On my profile, I have 'reviews' and 'return reviews'. What are return reviews, please? Also, I can see that I can change my profile image here in the forums, but I didn't see an option in the main site. How do I do that? Thanks a lot! Sorry if I am posting in the wrong section.
