Doing some InfoPath and used the substring function with a nested string length function to remove the trailing semi-colon from a username
The username was stored in a list column called Workflow_To Notify
The substring function takes three arguments
1 - The text string which in this case is defined in the @workflow_ToNotify attribute
2 - The starting point - InfoPath starts counting at 1
3 - Use this with string-length and -1 to remove the last character - in this case the semi-colon
