Bethany, I have found this to be the case with many areas in the OnProducts.

Hello: I'm finding this suggestion over two years after it was submitted. I don't see any notes about implementing it and the votes aren't very high, but this seems like a basic functionality that should be part of the Directory. An alum who only knows their former classmates by the name they had while enrolled is going to have a difficult time finding who they're looking for if they haven't kept up with them.
