A facility in EstimatorVJ allows you to send an Email to anybody you wish right from within the program. You can also choose to include a backup of the current project in either zipped or compressed format. Use this to painlessly send another workmate or even yourself at home/office, a backup of any Project you are working on.

Click on the Email button in JEstimator, enter the appropriate Email addresses, Subject, and Content information, then click send ? without leaving the program.
Click whether to include a 'zipped' or 'compressed' backup of the current Project, and the project will automatically be backed up and attached to the Email.
