Yes. I've already written a Greasemonkey script to do just that.
If anyone's interested, it's:
var welcome = document.getElementById("welcome"
).getElementsByTagName("h1")[0].getElementsByTagName("a");
if(welcome.length > 0 && (welcome = welcome[welcome.length -
1].firstChild.nodeValue) != null)
document.title = welcome + " | " + document.title;
Edit:
Should work for most non-forum pages too now. I like it the other way 'round:
Suggestion for a feature. | VGChartz.com | Forum
If you want VGChartz.com at the start, swap welcome and document.title at the end of the script.
