This is a link to the first part of a very useful and informative article on the subject of partition size increasing, size reducing, and moving.
If someone spots part two they might add it in a post in this thread, thanks.
http://www.ibm.com/developerworks/linux/library/l-resizing-partitions-1/index.htmlIt is also available in PDF form for those who might wish to keep it.

EDIT: Thanks for posting this Krisbee
http://www.ibm.com/developerworks/linux/library/l-resizing-partitions-2/index.htmlThe second article covers resizing LVM and troubleshooting techniques.

On the same subject, as well as Gparted in our repositories, there is also "partitionmanager" ... KDE Partition Manager.
I have not used it but what I have read indicates it is good.
