where is elgg front end website?

I installed ELGG on my local PC and logged into admin section...but where is the website front end? I mean when I go to http://localhost/elgg it asks for me to login!!!

Like with other scripts...Joomla, Wordpress, OScommerce....there is an admin section and then there is website front end which it automatically installs.....any changes made in admin are visible on website....so I want to know where can I access that website front end?
