Welcome to the Mechbunny Tube Script demo site.
Write access has been disabled to the database, as well as to the harddrive of the server for this demo site.
This means that you will not be able to register on this site, nor upload videos, nor perform any sort of tests like this. This is done so that no one can delete any of the demo content, upload anything, add to favorites, delete anything, and so forth. This is done to insure the integrity of the demo site so that it looks the same for the next visitor. On a live site, all of this functionality will work as expected - it is only disabled on this domain for demonstration purposes.
