You have to get rid of Mtgox in Chart !.
Will you fuckin' ban Mt. Gox from your site? I don't even want to explain why.
Could the newbies please pipe it down a bit.
You already got an answer by the site owner: Mtgox will be removed if (and only if) over a longer period of time there is essentially no trading going on there anymore. That condition clearly isn't met (yet), so it stays (for now).
