Ok, it was easier than I thought...I just added bits.wikimedia.org to the --domains option!!
Now I can retrieve wiki pages...
I wrote a script to download pages based on the browser's bookmarks named OFFLINE and a WAF to display them (landing page with dropdown menu+content window).
It's nice, but if a user must add domains to a whitelist if he wants to download a page similar to wikipedia (images hosted somewhere else).
I can provide a small whitelist based on the pages I find having problems with, but I can't provide a comprehensive list.
So, this needs a *bit* of user interaction.
