Project page is a portlet page, with a default set of project portlets (fig. 1), which cannot be deleted by users. Only the system administrator can delete the portlets. The set of portlets depends on the user roles and general settings, configured by the system administrator. You can add other portlets to the project page.
This portlet (fig. 2) displays the general information on the project: stage, start and end dates, manager and roles. You can add reminders to the project start/end date, if necessary. Note, that reminders work only for upcoming events.
