Contribute 3 includes a set of out-of-box Contribute Publishing Services (CPS, part of the Web Publishing System or WPS) for logging, e-mail notification, and user management. But did you know you can create your own services too? The real power of CPS is unleashed with custom services that extend and integrate Contribute in exactly the way you want. Tom Lane has posted an article on using ColdFusion to create a custom CPS. See http://www.macromedia.com/devnet/contribute/articles/custom_cps.html.
