"Maxlength allows you to set maximum length of any field on any form making use of the form API. This includes fields created using the UI. (Example: any text field on a node)
In D6 Maxlength allows you to set maximum lengths to the body, title and CCK textfields of any content type (node).
When the maximum length is enforced for a field, while editing content of that type some Java Script will countdown how many characters are left, also if the Javascript is turned off, it falls back to form API validation."
