How many new users, by week

To generate these charts, we use the excellent RGraph library. Please be aware these charts rely on HTML5 features (such as canvas) and therefore you must use one of these modern browsers:

• Mozilla Firefox 3.0+
• Google Chrome 1+
• Apple Safari 3+
• Opera 9.5+
• Microsoft Internet Explorer 8+ (see note)
• iPhone (text support from iOS v4+)
• iPad (text support from iOS v4.2+)

If you don't use a modern browser, you will not see the chart.
