Does it do anything different to your add HTML
instructions, Varkgirl?
Not really... Well, I mean, it makes it so you don't have to look at the html code. But it basically does the same thing. I think you put the code in the iWeb page and then the app somehow converts it to code after publishing.
I like MassReplaceIt - can do the same thing for free 🙂

(nothing against the creator of iWeb Enhancer - a nice little app for those who want/need it!)
