All of the non bug related threads for twhl4 are closed due to inactivity, so hopefully it's possible to merge this into one of those...
Anyways, I just noticed the twhl logo is designed to look like the menu items on the half-life menu (even has the mouseover bloom), and it looks quite nice. I think the site overall would have a more polished and theme consistent look if all of the buttons (on the header at least) were also styled similarly.
