Need to have a scheduled eMail reminder and a "flag" system to mark/flag members whose personal profiles need to be reviewed at a later point in time by the admin.

We have members that need to do certain tasks like updating their profiles and provide new pictures in albums. I would like to just flag/mark the specific member for a later review by the admin and then receive an eMail with a reminder to once again look into the specific profile. Also in the database there should be a marked icon like a flag, star or anything that indicates this profile is "under review"...
