Hi! I'm a german guy, so my english is BAAAAD and I hope I'm at the right adress.Sorry if not.

Is there a possibility to enter a webpage, which is locked by a password (so you have to be a member to enter) ?

Thanx!

It is possible, but not necessarily easy.
If the password is validated by the page in a javascript, it could be a rather simple "looking at the code, reversing" excercise.
If the password is validated at the server, it would entail a hacking excercise: gaining control of the server's script processor, not trivial.
