Hi,
To check which metapedia term got changed and who changed it we can set a email notification in CMC & Information steward.
CMC steps for email notification:
To set up a user email address for email notifications:
1. Select Users and Groups from the CMC Home drop down menu.
2. Click User List from the navigation tree at left. list of all users appears at right.
3. Select the applicable user name and click Manage Properties .
4. Complete the Email parameter with the appropriate email address.
5. Click Save & Close.
IS steps for email notification:
go to Manage--->preferences-->check mark the email notification button-->save it.
Thanks
