Sign In vs Login

Hi all
What is the difference between the "Sign In" vs the "Login" link at the top right?

I want to take both links off. I have unpublished "Login" but can not see a way to switch off the "Sign In" link.

Thanks for any help

Please look at template settings, the 'Features' tab, there you should see this options >> http://d.pr/i/LzTY

where you can enable/disable this part of template.

My question is the opposite, I would like both links to be visible. In my case I would like to change "Sign In " to "Sign Up". Where is the file path or admin backend to do so on joomla 3.0?

You wrote

so I thought you really want to disable this part. Anyway the Sign In can be enabled in template settings and the text you will find in template language file in root/language/en-GB/en-GB.tpl_gk_startup.ini
