My Projects page shows all projects in which current logged in user is assigned using Project Team option in Project.

A user can change his own email preferences by clicking on Options > Preferences icon.
A user can click on Options gear icon for View Project, Task, Team and Milestone pages as well but these options will be available only for those projects in which current user is either Project Manager or Team Lead.

Through project Email Preference page, a user can configure different email preferences as per the Project.

With View Project, a user can view/add/edit all the tasks and their progress, status in a single view. Further, can also view and edit Milestones, Team their hours booked for this project, and attachments uploaded to this project.
