How to use google analytics on soup.io

I'm running a soup blog for personal entertainment: soup.io is a great service for fast, quick blogging and has a great team, but it's missing statistics.
So, I've used google analytics. Here's how:

• Create a Google Analytics account


• Copy the tracking javascript (new version)


• Edit your soup description


• Enter html mode


• Paste the javascript code inside the description, then save.

Here you are, google analytics up and running.
I think you should not edit the description again, but I'm not sure.
