With version 5.6g, you can include 3 additional fields in Word letters. The three fields are PIN, Username, and password.
However, there's one difference between this upgrade and all others. When preparing merge letters in word, we use a special data file named LetterVolunteerData.vrd. That small file cannot be included in the live update, but does install automatically from the 5.7 CD. It is only used when designing Word letters, not during the actual merging of those letters.
It's a simple matter to put a new copy of the file LetterVolunteerData.vrd into your shared documents folder.
Now, when designing merge letters you can include the three new fields, PIN, Username, and Password. Begin with a Volunteer Do-It-Yourself spreadsheet for your data source.
