In the second page of the Join Project Wizard you will select a name for the development stream and identify the stream to which you will deliver your work. By default, this is the integration stream.
During the project environment setup, Rational® ClearCase® LT created a projectwide, shared integration stream. When you join a project, Rational ClearCase LT creates a development stream to track your work.
A useful naming convention is to include your username in the development stream's name. For example: jdoe_denali_release, where jdoe is a developer's username and denali_release is the name of the project you are joining.
