This is a privatly managed site running on private hardware. It does not belong to any business, nor any network provider. I have taken basic security measures to protect the site against unintentional damage, but to make sure that no serious attack would succeed, simply is not worth the effort, since the tests necessary to accomplish this would take more time than bring the damaged site up again. So, if you really try to screw it up, you may succeed, but you won't earn much fame for that anyway (maybe nobody will ever notice...).
However, if you should notice security leaks or problems, please drop me a line or two.
