That is the point I DO NOT WANT DROP BOX sending emails to anyone ...how do I stop that?????
If you use the tools within Dropbox to invite people, you CAN'T stop it from sending emails. That's the point. In order to invite someone, it has to email them. So, if you're just sending them shared links, create the link and email it yourself. Otherwise if you invite someone to a file or folder, Dropbox will send the email and you can't prevent that.
