If I click users at the top right, then search for a user profile by putting their name in the search box, I get another page with another search user box with no results returned. However, if I again put in the user name, I get the correct profile.
This is a little confusing because the first page returned gives the impression that a profile for that user doesn't exist.
Also, it would be nice if I can type in one word, and get back user names that contain the name either in the Christian or surname. At the moment, I have to type in the whole name correctly, although it ignores capitals which is a step in the right direction.
