Finding and downloading add-ons

The most common place to look for third-party products is the Plone.org products area. Most mature products list themselves here. The Plone Software Center that powers the products area provides several tools for product authors, including a roadmap tool (like the one Plone itself uses), and an issue tracker (powered by Poi, which of course has its own issue tracker) and a documentation section (powered by the PloneHelpCenter, which also powers the Plone.org documentation section where you are probably reading this). Not every product uses all of these features, of course. Most products will post a description of the project and usually also installation instructions in their products area. Be sure to read this. Many products will have other dependencies, or requirements for third-party products. Make sure you download all the necessary components.
