The flame Xml format allows you to save your identity with each flame. Since these values are seldom likely to change, they are kept here to avoid cluttering the main UI with additional fields.
These fields are entirely optional, you do not have to identify yourself if you don’t want to.
Note this is not tamper proof. There is nothing stopping someone from taking your Xml and altering these fields.
Your identity such as your first and last name.
A link to a website where you can be reached or your art is displayed.
A nickname or handle that you use which can be associated with your art.
