Login Switcher

This Greasemonkey plugin works in Chrome and Firefox. The purpose is specific to Windchill but could be programmed to work for any website that you need to continually login to with different users.

—-
Do you frequently switch between different users in Windchill, have you ever just wanted to log out. This script adds a
configurable list of links to the top of the page (specifically for 10.0) allowing you to switch users or logout with a single click.
