Personal nodes are often a space between a personal journal, mailbox and biography for an individual user. A good example of this would be Cloud Wiki's primary developer, Scott Dunlop, who tends to keep information about his Kabuki Server characters, to do lists and contact information there.
Be respectful of other peoples' personal nodes, and only edit them thoughtfully. People tend to be defensive about their personal nodes, and will often revert inappropriate changes. Respect this, as it is the only place in a wiki that a person can really call their own.
This node is a part of the cloud wiki manual.
