Hi, 

I am not sure how IOM matches on the default duplicate criteria. 

If Individual Constituent

First Name = length 4

Last Name = length 8

City = 5

Zip = 4

How will this match a constituent in the Raiser's Edge 7?

e.g. John Walkerton Sydney 2000

will this match to 

Johnson Walkertown Sydneham 2000

automatically if I choose to auto-match exact matches?

What settings do others use as best practice?

thanks, 

Simon.
