Lotus Notes possiblities are founded upon the concept of NotesDocument, which is just like a paper document. Paper documents are flexible because they can be updated in a breeze. For example you can add a date stamp to any paper document when it arrives to you, even if it was not created with a white space for that purpose. NotesDocuments can be individually changed as needed, both pasting in and cutting information from them.
