2. "Unique Field per User" validation
Aside the validation rules included in the previous revision, RSForm!Pro rev. 42 comes with a new one: "Unique Field per User".
When this validation rule is selected, RSForm!Pro won’t allow the submission of 2 identical field values per user. The validation is applied for both type of users, registered by checking the user id) and guests (by checking the visitor IP).
