What happened to Panda Passport?
And so it has with Panda Passport: WWF's first global online campaigning tool.
Invented in 1998, Passport has had many successes on the ground over the years saving everything from tigers and whales to lakes and seas.
But as Passport enters its teenage years, like all teenagers, the time had come for change.
After that came the myWWF Action Centre: a place where your actions were more integrated with other things you may take part in with WWF. Things such as making comments on news stories or, in a few short months, buying virtual gifts for people you care about.
So what will come next?
Hopefully, we will pleasantly surprise you.
