The installer download page (after you click "Get Installer") is a permanent URL or permalink. You can copy it and send it around to easily share a Ninite installer.
Here's an example for Google Chrome: ninite.com/chrome
Or one for Firefox, Flash, and Skype: ninite.com/firefox-flash-skype
These links are great for doing remote tech support for friends and family.
You can also link to the Ninite homepage with your apps selected.
