word press plugin requires permalinks

[SantaRosaDesign]

There's a word press plugin I want to install that requires this "You MUST have permalinks turned on. It doesn’t really matter what structure you create for permalinks. "

How do I check if this is turned on? And if it's not turned on, can I turn it on somehow or is it likely that my host only has the priveledges or permissions to turn this on?

Permalinks are just the url to the various posts you enter into the WP blog chronology. I am sure it is activated, here is more info: http://codex.wordpress.org/Using_Permalinks
