» Easy to install. The installation process is a simple and painless procedure—just upload the files, include the Javascripts, and add an empty div. YShout does the rest of the work for you.
» Customizable. Fully styleable via CSS, you can tailor YShout's appearance to fit your website perfectly. It also comes with a control panel, so you can customize many aspects of the functionality.
» Standards Compliant. YShout is the perfect complement to your standards-valid website. It outputs proper XHTML styled by completely customizeable (and almost equally valid) CSS. YShout is also non-intrusive, so you can stop worrying about ruining your perfect markup. Just toss in an empty div and you're done!
» AJAX-Powered. Yes, it's a buzzword—but for good reason! With AJAX, YShout eliminates the need to refresh in order to keep up with new messages, and does tons of other nifty things without reloading the page.
