Usernames in Shared Workbook

[Shogun]

I update a file that is shared and i check if users are in the file before unsharing it but im curious if i can pull a list of the users in the file and if possible email them. Is there a way to reference the usernames of the people in a shared file?

So i found this example but it only works for 2003/97 Does anyone have any other links that might help?
