prosilver contains a JavaScript file called forum_fn.js which contains the following code.

	/**

	* Adjust HTML code for IE8 and older versions

	*/

	// if (oldBrowser) {

	// 	// Fix .linklist.bulletin lists

	// 	$container

	// 		.find('ul.linklist.bulletin > li')

	// 		.filter(':first-child, .rightside:last-child')

	// 		.addClass('no-bulletin');

	// }

This is supposed to be a fix for old browsers but it's commented out so there's no point in keeping it in prosilver as it's not doing anything but taking up space.

Besides, IE8 isn't even supported so it's redundant.
