How can i?

How can I block the time and last login off my profile I have a person watching the time I last visit on eccie and its creepy so how can I stop the time that I last visit and logged in????
There is an option to never show you as on line. That may do it but not sure.
Left side of the screen, click User CP, go to Edit Options, click "Invisible Mode" scroll to the bottom and click Save Changes.
thanks!
