I have a website that doesn't have a title. How can I add a title after I've already published it?

I used sitebuilder to create the site and yahoo is my web hosting service.

Place this meta tag at the top of your html under head. It should be the first meta tag.


%26lt;title%26gt;Your title here%26lt;/title%26gt;
