Field modification moderation

Hello! I've take a look at documentation but can't find the specific section. How can i moderate fields of users when they change them after registration?
Like they register with a name then decide to change the name later in their profile, the users can do it but i need the admins (or moderators) to receive a mail and then approve the modification.
Is this possibile? How?
Thank you

There is no individual field moderation except for image fields.

Ouch, really hope to have one. Is possibile to have at least a mail notification when a user update his profile?

EDIT: ahhh yes, i can do it with this www.joomlapolis.com/addons/cb-profile-update-logger ,right?

Yes, you can use CB Profile Update Logger to be notified of profile changes or use CB Auto Actions with the following usage.

Global
Triggers: onAfterUserUpdate
User: Automatic
Access: Everybody
Conditions
Field: Custom > Value
Custom Value: [var1_FIELD_NAME]
Operator: Not Equal To
Value: [var3_FIELD_NAME]

Replace FIELD_NAME with the name of the field you want to check if is changed. You can use whatever action type you like, but in this case you'd just use Email type.

Nice, thank you. In your opinion is better to use CB profile updater or Auto actions?
Does the CB profile updater write in the mail the old and the new values or just tell moderators "user X has changed something"?

It's easier to use CB Profile Update Logger as it has minimal configuration. Auto Actions is more complicated and requires an auto action per-field that you want to monitor for changes.

The email includes what was changed. Email is a language string so can be overridden as well to customize it.
