Logout Customisation Hack Question

Hello All!

I have a membership site sitting ontop of a wordpress.org 3.2.1 installation.

I am attempting to customise the loggin out proceedure using simple image buttons that execute the logout command. There are widgets that do this work, but they show information I do not want to show. Hence my attempt at a custom approach.

This link almost does the trick. However it sends the user to a page which states
“You are attempting to log out of {Website title tag prints here}
Do you really want to log out?”

I would like to find a way to avoid this page appearing. Here is the link I am using as the ‘execute logout’ link. Is there a way I can modify this to make it do what I want?

http://WEBSITE.COM/wp-login.php?action=logout&redirect_to=http%3A%2F%2FWEBSITE.COM%2Factivity%2F&_wpnonce=f444deeaf3%22%20target=%22_self%22

I have removed the website address for privacy and replaced it with WEBSITE.com

Thanks for any help
