Is there any module around where I can assign role to user for certain period of time.
For example role name: some_content_viewer or some_content_editor.
And I want to give some trial access to this role (for example 3 months). So this user will be granted with role some_content_editor from 24-sep-2007 till 24-dec-2007.
If I grant role to another user tommorow, that role should be active 25-sep-2007 till 25-dec-2007.

Thanks for replying.
