In addition to the extensions available on the Macromedia exchange, designer/developers have created more Dreamweaver extensions, templates, and other goodies that can be added to the program.
Dreamweaver Exchange (www.macromedia.com/cfusion/exchange/index.cfm?view=sn120). This Macromedia site is a great place to start when you're looking for Dreamweaver extensions. The listings include extensions from Macromedia as well as from third-party developers. Be sure to read the comments by people who have actually used the extensions before you download, install, or purchase an extension.
Project Seven (www.projectseven.com). Project Seven is one of the best commercial sources for Dreamweaver extensions and design packs.
Templates2go for Dreamweaver (www.templates2go.com). Designer Linda Locke offers four packages of predesigned Web sites for business, e-commerce, and personal use. Each package includes 25 sites.
