A contributor is anyone who contributes to the site. Writes on forum, reviews a product, rates products, rates reviews, etc. An advanced reviewer is one who has either graduated from the mentor program or has written a few reviews on previously owned items from or same as the ones on Edens, you can submit them for an upgrade vote. I personally recommend the mentor program, it helped me immensely when I started on this site. Please feel free to message me if you have any questions about site navigation, terms, etc. I am always happy to help new contributors like yourself!!
Welcome to Edens!! Hope you have a blast and enjoy participating in one of the greatest and most generous sites!!
