Tested with latest: Firefox, Chrome, IE, Opera and Safari
Waiting for your feedback 
There is now a short maintenance break before the site update. All active users will be forced to logged out.
Version 0.89 changes: password can be now changed. I also corrected several bugs and added some new security features.
Server OS is now being re-installed. pre-site will be back asap.
I’m doing some necessary maintenance upgrades. Pre-site will be back asap.
Update 12 hours later: the box won’t reboot after system upgrade. I have found people suffering from the same problem: something weird happened with latest Ubuntu 10.04 update. This is most likely related to video driver/splash screen which I wouldn’t need anyways. It just won’t continue to the actual boot sequence with any kernel-image… Pls be patient.
