Which variable to use to display profile latest updated ?

[Quantnet]

I like to display the time when a user profile is updated by the admin. For example, when the admin move user from usergroup X to Y, I like to display the time when the admin do that.

Many thanks

You would most likely have to add two new rows to the user table, one as a timestamp and one as a userid/username colum for whoever updated. Then you'd also need to save this data, and display it.

Not sure if thats all possible without some code modification.
