i want to give a suggestion. why not make an ad generator here. we can put our color that we like. then the x10host ad code will appears. so everyone would have a color that suits their forums.
I feel that they might say you can't change the size of the ads, however, a colour changer would be nice, as that way you can change the colour and blend it in with your site
well i believe the problem is, is it's Yahoo Publisher ads, and therefore there isn't any color chooser as it's still in the private beta stage i believe
