For example, because I've chosen "case_sensitive" as my user name, no one else may choose "Case_Sensitive" or "CaSe_SeNsItIvE" et c. Meanwhile, a request for "Case_sensitive" will fail.

It displays your posting history on a chart. From the left to the right, the posts get newer. From the bottom to the top more popular. There is a little ? on the upper right of the page which leads to an info page.
