The Scriptplayground team is currently developing the next version.
In the mean time you can find the previous version in the archive.
You are probably curious why we would pull the site offline and archive it. Well thats simple, version 2 of this website was developed back in 2004 and as you can imagine is very outdated. Even-though it was custom developed and constantly updated a few security concerns have cropped up.
Rather than spend resources having the team patch version 2 we have decided to focus all efforts on the update. This will result in a much more feature-packed and solid version 3. Take a moment to bookmark this page and follow Scriptplayground on Twitter for updates on the development process. We will be releasing more information about the next version shortly.
