If you use FireFox as your web browser, it's not too difficult to change how links are displayed on TTOL. The first answer to the question at https://superuser.com/questions/318...f-a-site-in-firefox-with-usercontent-css lists five steps to get you there. However, instead of adding the sample content in the answer to the userContent.css file, add the following text instead.

Code
@-moz-document domain(www.traveltalkonline.com) {
	.post_inner a { text-decoration:underline!important;color:blue!important; }
}


This should make links in posts show up underlined and in blue.
