Use notes and links to track the project information
Notes are useful to remember important details.
Hint: start note by writing the date and the circumstance (e.g. 10/09/2006 - Weekly meeting). It can be helpful to number the notes, too.
You can define links to other important documents related to the project (project charter, product description, project deliverables, project objectives etc.). Attach brief, relevant descriptions that will help you to identify the link's target.
