I would just to let you know that this site will remain closed for at least a couple of days, because I'm moving it to a new server.
After many months of bad performances and also some JS and PHP injections I have decided to shut the current hosting service and buy a dedicated server.
This new solution is costing a lot more... but I hope to definitely solve all performances issues and bad server configuration.
I will try to release a new beta before moving, so you can play with it while this site is closed.
Unfortunately I really need to close the site because I not only need to move files and db, but also I need to switch registrar, and this will cause a service blackout for a small (I hope) amount of time.
I will try to have all things sorted out before this weekend.
