Mini-profile cards
If this web part is enabled in Central Admin, mini- profile cards is displayed wherever a user’s name is displayed.

The count and thumbnails of colleagues in common are displayed and the link to add this person as a colleague will display (if applicable). The Send an email link makes it easy to contact the person.
