When Macromedia released Contribute 1.0 last year, we were impressed. It gave nontechnical users a nearly foolproof way to update the content of a Web site while protecting the integrity of the design and underlying code. Less than a year later, the company has released Macromedia Contribute 2. Thankfully, Contribute 2 is not a dramatically new version of the product. Satisfied users will find that the program still has the same streamlined workflow, wherein you browse to a Web page, edit content, and publish new versions. But the new version makes it easier to add e-commerce links and Flash files to a site.
