I don't have Dreamweaver and I don't have Kompozer and I don't know how to write in HTML...That is why I have Yahoo sitebuilder. And I am using it on my old computer..YAHOO knows where to find me when it takes the fee out of my AMX card account.. I think Sitbuilder is a SCAM..
Install applications like Dreamweaver, Kompozer and notepad++ in your new computer. These editors can help you build your website..
You a download one. I just use weebly its easy and if I need something I just downlosdthe source folder ad edt it and uplodit to my own server
