I have used your Mass Stay in Touch and I am pretty much comfortable with the module. You guys did an excellent job in order to built this feature which is nearby similar to the Salesforce Mass Stay in Touch minus Salesforce Mass Stay in Touch Limitations. Here I would like to request you if you guys can enhance this module in order to identify who has updated the Mass Stay in Touch information and who did not. In that way, we can keep track of the contacts who has updated their information and also our approval process will becomes more informative for us.
You guys are awesome!!!
