Generally speaking if you update your node to reflect what people have said to you, politeness would dictate that you put

Update:.... description....

in there to describe your update.

Not only is this polite but it helps those reading the node to understand the context of peoples replies to your node. For example, there was a typo in this node so I would put:

Update: fixed typo

However, thats purely from a code/opinion point of view. In the context of your example, surely thats what NodeReaper is for?

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
