If you open up Dreamweaver--then click on the
help menu--you will see--
Guided Tour | Lessons | Reference | Using Dreamweaver and several other good tools. You will also find a link to the Macromedia Forums Online.
There are several Dreamweaver Books out there but I have never purchased any of them.
You can also find some good--and fairly cheap--templates at
www.TheTemplateStore.com &
www.DreamweaverTips.com
I use
UltraDev--which is the version of Dreamweaver with all the bells & whistles. What version are you using?
