User accounts registered in the last few days were lost during the server migration and upgrade to Drupal 7. This will not affect your ability to run GameStart if you already registered your account during the first editor launch, but you will need to recreate an account to publish content on the site.
Sorry for the inconvenience.
Now that the site upgrade is mostly complete I'd like to talk briefly about the state of the project.
GameStart has been in public Beta for a so long period during which I had to implement new features to support external projects that I am almost tempted to roll it back to Alpha. Several new features have crept in and some drastic changes have broken both parts of the workflow and of the interface.
The software is still usable but its stability has worsened significantly. After the current work on mobile platform port I plan to freeze all feature development, branch the code base and concentrate on bug fixing.
This is probably going to happen by the end of January 2012.
Stay tuned!
