It may be desired for a project creator to have full control over their own projects only, this can be done using the following process.
Log in as System Administrator and select the Options button of the Users Section.
The value drop down default is empty.
Select a Project Level Group you wish to apply to users who are project creators and press Save.
Note: In the example provided there is a group called Project Manager, as the setting up of user groups and roles are completely customisable you may have a different name for the group you want applied. Bare in mind this new dialog satisfies the use case when if you add a new user and give them the create project role you now can make them project manger of the projects they create.
Once saved if that user logs in and creates a project they will have the roles of whatever group you have set in the option menu for the created project only.
For example if they are a View user and you give them project manager group rights as the option, then for any created project they are the Project Manager of said projects but for all other projects they have the default view rights.
It is highly recommended that the Admin User reviews all users groups and roles if they havent done so previously.
