There are 3 access right levels for each record or note:
Members of departments, or users designated as readers may read the contents of a note or TeamGram record (contact, company, deal, etc.)
Readers may also write comments about any note they can read, or add notes to any record they can view.
They may also access search results containing these records.
Editors may do everything readers can do. In addition, they can also change these records, or delete them.
Owners can do everything editors can do. In addition, they can also decide who will have reader or editor level access, and may even transfer ownership rights to another user.
A user automatically becomes the owner of any object he or she creates.
