I have used your Mass Stay In Touch and I am pretty much comfortable with this module. You did an excellent job in order to built this feature similar to Salesforce Mass Stay In Touch minus Salesforce Mass Stay In Touch Limitations and I would like to request you if you guys can enhance this module so that we can Mass Approve the updated information received from the Contact through this functionality.
