I tried using httrack to download my phpbb forum, but no matter what setup I use, I cannot get it to stop downloading the entire wikipedia site as well, and many other websites whose links are anywhere in the forum...
What I managed to do it make it download the index page only, but that's not good either.
I thought that setting
+forum.mysite.com/*
in the Options->Scan Rules would do the trick, but it went on to download the entire wikipedia again :(
