Comments from some of those who selected Nvu as one of their Top Tools 

“The familiar WYSIWYG interface of NVU makes it very easy for students to create web pages without the need to master HTML directly.  In addition, having access to the HTML code and a CSS editor is very useful for engaging the more advanced students”  Patricia Donaghy

“This I found to be a master piece to design web pages without having any knowledge of HTML, XML, etc., Also, ability to upload the designed page is another attraction.”  N B Venkateswarlu
