In the latest Seshamo version, released this morning, we have completely redesigned the user page providing the ability to search for a given user by either username or real name.
Search User by username or real name.
We also added the ability to sort the list of users by profile, join date and username.
Order User list by profile, name or join date.
The first sorting option, profile, probably deserves a few more words. Starting from this release, we started to show off a ranking parameter based on how much your profile is up to date. The more information you provide, the higher is the ranking.
We have been using this information for quite a while to create some internal super-secret features, but now we decided to open it to public and give you the ability to sort the list of users by this parameter. Sorting users by profile, you would expect to view users with the best profile at the top of the page.
Do you want an higher rank? Jump to your account page and start customizing your profile now. Don’t forget to upload your picture… it will give you a super-duper boost. 
[...] As you probably noticed, the new release contains some small changes in the “Users” panel. We switched from a single window to a tabbed window and we are now spotting the best profiles using the profile-rank. [...]
