I will check with the site administrator, but I hesitate to "shut down" this thread as it doesn't really violate any of the sites guidelines, nor has the conversation taken a really nasty turn. Minus a few cheap shots this conversation has remained relatively civil. I would hate to start a precedent of shutting down threads that have become annoying. A better solution is just to ignore any further posts and let this thread die a natural death, IMHO.
As to the "ignore" feature, I will bring it up and see if that is something that the site/and the host does support.
