How to see who logged in today

Hello, i can see in the back office how many people are member and so.
But haw can i see who logged in today, this week or this month?

Thank you. 

Same place - Admin - Members - Geeky view

Sorry, but i can't find it.
I don't see Admin, where i must see it? In boonex menu? 
Maybe i did something wrong...
 

on the left hand side of the page you have taken the screen shot from, there should be a block named Members, click on that and then click on Geeky as mentioned before by ProfessorSr

You also have last activity, last join, etc that you can switch to in the dropdown box.

It appears you have changed your admin menu from the default.  Normally Members is at the top of the left hand admin menu but I don't see it in your screenshot.

:( maybe i deleted, can someone tell me how to make one new?
it must be a link or so?
