All the other forums don't see IE6 as a problem, and don't look ugly at all when i use them with IE6 at uni or firefox at my house.
This forum, other than minor personal differences (such as an ETW banner here, and different color scheme there), looks the same as all the other forums as well.
I see no reason why you can't use the same setup as the other forums on the HG network to allow for IE6.
