Include the page address within a plugin

[eviljoker7075]

Hey there, I am looking at creating my first plugin but have very limited php knowledge... Is there a way to insert the url of the current page?

For example say I wanted to add a link to email the current page to an admin, how could I insert the address into the below?

<a href="mailto:siteadmin@site.com?subject=Nomination&body=[Thread URL Here]
