The PCS WebGantt^© download is a fully functioning demo version.  It contains all the functionality required to specify project schedule information and create a Gantt chart.  However, unless you register your copy and obtain a registration number, you will be limited to creating Gantt charts with five (5) tasks or less.

If you haven't do so yet, be sure to register your copy of PCS WebGantt^© to unlock the full capabilities of the product.
