– The ability for users to leave comments and rate each project.
That’s going to be a great addition. Few review websites allow visitors allow users to rate and leave their comments on the reviewed casinos/projects and that’s why people don’t trust them. This will make your website more credible especially if you won’t remove those comments even if you don’t like them.
– Sorting the list by rating.
Are you going to use visitors/users ratings or your own to sort projects?
