Hi,
There is an interesting feature in the community known as User Rank which based on the contributions we get rank like Valued Contributor, Trusted Contributor, ... .
It would be nice to create some icons for each rank and when a user reach each rank add the icon to their profile.
Initially it could be in the profile page but in case it is technically possible, it would be nice if add it when we mouse over or beside the user's profile in each post.
