The Billing System has had a rework to make it easier for you to start or change a subscription to RuneScape.
The first thing you may notice is the change to the front page. From the 'Membership' area on the left, you are able to access two new sections. 'Billing FAQ' will tell you everything you need to know about subscribing and paying for RuneScape whilst 'View my account info' gives you the latest information on your account including the number of days credit remaining.
When you visit these sections you will also notice another change: the Billing System has been redesigned. You will find that actions now require less scrolling and clicking, reducing the amount of time you spend updating your account.
The pages also look very different, with each of them being headed by a logo that says 'Jagex' who, as you will most likely know, are the makers of RuneScape. The pages will all still be on a www.runescape.com web address and, even though they may look different, they are as safe to use as always. So, when subscribing you will be able see the padlock symbol in the usual part of your browser, which indicates that any transaction or information passed is encrypted and secure.
