If you have other team members also and all of you together interact with people via forms, at some point of time you may need all of your team members to be aware of some important information.
Sometimes you may have to handle different people in a different manner. In this regard, private notes are very useful.
FormGet allows you to put an internal note that will only be visible to your team members.
Internal notes help when you want to share something regarding the message sender with your team members only.
Whereas a public reply will send your reply to the message sender and also be visible to your team members.
