what does the option "unique logins" mean ? which will show after choosing report type: "Logins" then submit the form to show the table.
It's the metric you use if you want to estimate how many people are using your site. It shows how many different usernames have been used to log in. E.g., if the user "foo" logs in 3 times and the user "bar" logs in 5 times, they count as 2 unique logins: "foo" and "bar".
thank you Mr. Eric .. I got the idea now ...
