The submenu Customization of the Organisation settings allows to

  • change the labels of "Projects" and "Users"
  • create specific projects custom field(s), whose values can then be entered in each project (view "advanced")

Notes regarding labels:

  • you may choose to change either both terms or only one of them.  As the terms are used both in their singular and plural forms, you have to enter both information. 

  • the renaming applies then to all screens, with the exception of the Knowledge base

  • the renaming applies only to the account (main) language.
