wget --reject -R troubles
 

I'm trying to download a backup of a forum (not this one, don't worry). Most of the threads save as “f-17.html”, as they should. The problem is that wget keeps following the link for logging in under different filenames, e.g. “f-8.html?login=1”. I should mention at this point that all of these login files are exactly the same. So, how do I keep wget from downloading these useless files? I tried the -R option, but I just can't get it to work.

One more thing. I have a previous backup of the forum in question and don't want to redownload unchanged threads. Should just throwing -N into the arguments take care of this?
