How can I edit an existing .xsn form (pulled from a SharePoint site) so that it will send an email notification to selected users? For example the address of the person will be chosen from the 'Select People and Groups--Webpage Dialog'. Then, there will be a checkbox to select whether or not the user will get an email.
Can this be done in InfoPath? If so, how? If not, I have access to Visual Studio, but I'm not sure how to open the .xsn file in VS.
Thanks for any suggestions.
