In the constituent name format area, create another primary salutation flag. The two flags should indicate the "Primary Formal Salutation" and "Primary Informal Salutation". Depending on the mailing or correspondence being created, you may want to be formal or informal. For example, a formal mailing may be addressed to "Mr. and Mrs. William Smith" and the saluation would be "Dear Mr. and Mrs. Smith" while an informal mailing would have the salutation "Dear William and Martha". Without the additional flag, this is much more difficult.
