Yeah. When i open that in google chrome it gives me this.
The site's security certificate has expired!
You attempted to reach supertux.lethargik.org, but the server presented an expired certificate. No information is available to indicate whether that certificate has been compromised since its expiration. This means Google Chrome cannot guarantee that you are communicating with supertux.lethargik.org and not an attacker. Your computer's clock is currently set to Sunday, August 26, 2012 12:07:21 AM. Does that look right? If not, you should correct the error and refresh this page.
You should not proceed, especially if you have never seen this warning before for this site.
I know, It doesn't give the full effect without the bright red background or the wanring sign... But that's what it says. And that is what matters.
