Notification when updates made to MySQL

Have a website for 700 alumni fraternity brothers. Developed a system where each brother can update their contact information as well as their work history and life history. This can be viewed by each brother so we can know more about each other. (Not all are from the same era) These are secured pages protected by security assist.
I want to develop a recordset when someone updates their bio, so I can post a page that can show who has added new information about themselves. Also show a date they last updated, if possible.
Not sure how to write the recordset query.

I think that i figured this out by using a timestamp in the database and the recordset where the timestamp is >= CurDate()

Yes, you can have a timestamp field that will automatically update to the current time whenever the row is updated.
