Although this does not affect gameplay,
I post it here because it's very important.

Some of you may have read recent news reports regarding a security flaw in the Internet Explorer web browser – the default web browser in Microsoft Windows. This flaw is reportedly being used to steal passwords for various popular online games. We would therefore like to take this opportunity to remind all our players of a few important security practices: - If you use Windows make sure you have the latest updates installed. You can get the latest updates and security fixes for your computer from windowsupdate.microsoft.com. This will protect your computer against the latest security flaw. - Never visit a website that you are told about in-game, as there is a chance that you could be directed to a fake website. Fake websites are dangerous, as they can allow hackers to access your personal information, or expose your computer to viruses. Remember, it is against the rules to promote any website, either in the game or on the forums; if you see someone advertising a website in this way, you should report them immediately using the Report Abuse button at the bottom of your screen, and selecting Rule 11: Advertising/Website. - Make sure you have up to date anti-virus software installed. We also want to take this opportunity to remind you that you should never give out your password, or any personal information such as your email address or real name, to any other player, for any reason. For more information on security, please read this article. We want all our players to be safe, so please take the appropriate care. Thank you for your support, and Merry Christmas!

It is important, but when I read the news article's title, I was wondering whether or nor Runescape was going to recommend a different browser. That would've been funny, not sure if they are allowed to or not. On my computer, the updates pop up everytime, so I did not really find the post useful, it was just the same old stuff

Can someone tell me if they were allowed to say, for example, use firefox as an alternative to interent explorer?

Right, but if Jagex were to say "Use Firefox 3 instead of Interent Explorer 7" in their news post, would that be acceptable? I'm sure Microsoft would get annoyed.
