What is it?
Macromedia Dreamweaver - Dreamweaver.exe

What does it do?
Dreamweaver.exe - This is a WYSIWYG editor that makes HTML coding extremely easy. It also works as a great editor for really any web programming language. It helps keep the coding slimmed down and compliant which is something that frontpage simply doesn't do. Yes this is what I use for everything on this site from the PHP backend to template editing.
