I have posted these passwords and IDs here not intending to spoil your enjoyment of the challenge. They are freely available on various websites and forums. The real challenge is to obtain them properly, and a visit to certain forums explains what to do. I am still unable to do that, even reading the careful instructions! But unless you know the inner workings of headers, VB etc you will not be able to attempt level 5. To get to that page to enter the PW and ID needs skill and knowledge that only the real experts possess.
