RE: gant chart
Hi Tom
The easiest way to change the start date of your project is to click on Project-Project Information, and choose the start date in the project start date combo box.
If however you want to alter the start date of individual tasks, then you can select the task in question and double click to open the task information dialog. On the advanced tab you can set a date constarint specifying when the task can start or finish.
This is however not recommended as it can cause scheduling conflicts.

Stephen
