So I'm sure you're familiar with the popular PHP BB's used 
everywhere...  There is one I'd like to mirror which 
requires a user to sign in.  He then gets a cookie which 
allows him to read and post messages.  Is there a way for 
me to mirror those pages?  Copying the cookie to the 
httrack cookies file did not work, I think I need to 
somehow fill in the login info...
