We've been mentioning this for a while, but we've finally made the big step in merging the Greenfoot and Greenfoot Gallery websites. Essentially, the old, fairly creaky greenfoot.org site has been removed, and the greenfootgallery.org site has been moved across and put in its place. We've felt for a long time that the old greenfoot.org site needed updating, and we're pleased to integrate the user content -- your scenarios and your discussions -- into the heart of the Greenfoot website.
The first thing you will notice if you're a regular user is that you've just been logged out. That's an inevitable one-off consequence of changing the domains (your cookie is for greenfootgallery.org, but now everything is under greenfoot.org). If you've been logged in forever and have forgotten your password, go to the login page to sort that out. Apart from the logout, everything should be fairly smooth. All the old gallery URLs just redirect to the same place on greenfoot.org, and all important greenfoot.org URLs should redirect to the right place on the new site.
If you notice any problems (or you can't find some content that used to exist on greenfoot.org), post here to let me know. If your problem is that you can't login or can't post after the site move, then you can email me on nccb@greenfoot.org and I can try to sort that out for you. Otherwise: continue as you were.
