First of all I wanna thank you for this great Joomla component. Many advantages of your commenting system indeed, Ajax refreshless really rocks and saves too much bandwidth.

Everything was ok with the component except one thing, it doesn't produce valid XHTML Markup. I installed and tried both versions, 3.26 and 4.0 alpha, just to double check the problem. The older version 3 produces more errors in the Markup than the newer version for sure, but.. there are still Markup errors.

The errors I have found are located within the component's template files and more specifically:
[ul]
[li]JQdefault-emotop: 1 error[/li]
[li]MTdefault-emotop: 1 error[/li]
[li]SSlide-emotop: 1 error[/li]
[li]SSlideBoth-emotop: 2 errors[/li]
[/ul]
The problem is that you use in the internal script of JavaScript the character "[color=#FF0000]<[/color]". One work-around would be to put the whole JavaScript code, which needs this character "[color=#FF0000]<[/color]" in an external script and call it from the template; this what W3C suggests in such situations.

I hope you gonna fix this soon mate, because those sliding effects are pretty cool, especially if they could produce valid XHTML.

Keep up the good work!
