I apologise for the fact that I cannot host the script myself for you to view, this is because my host sucks. If you want to have a look at it running then you'll have to download one of the files above, extract it and set it up on your own server.
If you don't have your own server already set up then I would recommend installing WAMP5, which can be found here.
Should any damage or loss occur due to any of the scripts above, it's not my fault so don't come crying to me. Having said that, everything I upload here has worked fine for me so there should not be any danger, you have been warned though.
If you find any vulnerabilities that could be exploited or code that could be improved please do let me know, this is going to get put to use in the CLC and will most likely be used by many schools in and around where I live. I wouldn't want to let them down by handing over sub-par code.
