EBS: Managing proxy setup to grant access

If you have been supporting an EBS application for some time, one of the common issues is granting proxy access for workflows or approvals but did you know you can use proxies to grant access AS a person?  I did not realize this either until I read MOS article "How To Add People (Grant Access) Through Preference--> Manage Proxies Setup" from document ID 1378402.1 and now I get to think how I can bring this back to our environment!
