Given the nature of the people that attend the KWLUG, there is a high likelyhood that most of us have more than one distribution and/or disk partition to play with in the same hard drive.
GParted is a free disk partition editor that allows creating, deleting, rezising and moving partions.
It enables you to reorganize your disk partitions while preserving the contents of these partitions.
It is one of those rare Graphical tools that provide as much flexibility and power as their command line counterparts, reducing the anxiety associated with mesing up with your data.
But that description seems superfluous as I am sure most of us have used it one way or another.
