It's pretty cool that you can upload photos of people to search for them later, when there might be no contact information available! You have options over which database system (eMergent) it pulls from as well - I would definitely like more databases added!! Other than being able to pull pictures off Facebook or LinkedIn profiles we've never had enough info about someone before searching through this program so far; however some are easier then others because they contain names instead of just identifying numbers such an ID number assigned by social security cards etc..
Have not used cross reference much but think its quite useful if anyone has ever been working outside their church/company office and haven't kept up-to date phone contacts? Very nice way of finding old coworkers again without having to resort back into emails or facebook searches via google calendar ectetc.
