I was looking for a user with a Drupal role to contact me by IM. I found one! So I wanted to share.

Go to this URL to create the code for your Google App account:

http://www.google.com/talk/service/a/asu.edu/badge/New

Copy the code into a block of a Drupal site. Now anyone that selects the link from your site will be seen as a guest in your IM. You can set permissions by the Role's who you want to access the block.
