Using CSS you can make your own...
a {
border-bottom: 1px dashed brown;
text-decoration: none;
}
a:hover {
position: relative;
}
a span {
display: none;
}
a:hover span {
display: block;
position: absolute; top: 10px; left: 0;
/* formatting only styles */
padding: 5px; margin: 10px; z-index: 100;
background: #000;
border: 1px solid #F00;
font-size:8px;
color: #CCC;
opacity: 0.9;
/* end formatting */
}
Then use it as a span in the link:
The greatest site in the world <a href="htttp://cleverwasteoftime.com">is CWoT<span>Owned by BLiZZaRD. The Game site is the best ever!</span></a>
