Adobe Contribute CS4 allows Web site content contributors (writers, editors, artists, and other non-technical folk) to easily add to and edit Web sites, shielding them from the complexities of HTML and CSS. Users edit Web pages, usually but not necessarily based on templates prepared by a designer using Dreamweaver, in an environment reminiscent of a word processor. It facilitates the editing of text and images without the danger of accidentally breaking the design or organization of the site. The new CS4 version provides a sprinkling of useful new features, but overall, this is a mediocre revision.

Contribute is included in the Web editions of Adobe Creative Suite 4, and is also available as a standalone product. At first glance, this version looks like a big change from the previous version, Contribute CS3, but the change is really only skin-deep. The first thing that you'll notice when you open the program is that the user interface has a new grayscale, panel-oriented look, similar in style to the other applications in the CS4 suite. There's a new, largely useless Application bar right under the menu bar that runs the entire width of the screen. You can't remove it, though you can resize it. One drawback to the new interface for Mac users is that Contribute CS4 really wants to take up your entire screen. Opening a document on my 20-inch monitor causes all background programs to be covered up by Contribute's document window, toolbars, and panels. You can shrink the document window, but the toolbars and panels stick stubbornly to the top and left sides of your screen unless you manually move them elsewhere. In this way, the interface acts somewhat like a maximized Windows program, which isn't expected behavior on the Mac, and sometimes gets in the way.

Unlike previous versions, Contribute CS4 does achieve feature parity between the Mac and Windows versions. But Contribute's performance does not seem to have improved in this version, which is a shame, since it has always been a bit slow to connect to and begin editing pages.

Web page rendering fidelity has been improved, notably in displaying CSS (Adobe says that these improvements were made to match Dreamweaver's similar rendering enhancements). Unfortunately, the program's rendering is mostly unchanged, meaning that within the program, page display is still quite different than that of real Web browsers. Contribute's developers should have followed the lead of the Dreamweaver team and implemented the cross-platform WebKit (used by Safari, and in Dreamweaver CS4's Live View), to achieve more accurate Web page rendering.
