Consider this one just for you buddy.

I just added a forum hack so that users can now display a small country flag next to their posts. If you look at my name a small USA flag should now be showing up. Is this what you wanted or did you want me to actually get you an american flag avatar?

If you want a flag to display just go to your user Cp and "edit profile" then choose your home country and save. A flag should then appear next to your posts.
