I can only speak for WITHS2 Clubbox
and the way it works is that the clubbox carries the RAW (no subtitles) unless it is marked "hardsubbed", which usually placed under "hardsubbed" folder underneath each project.
So for softsubs, you'll need to come to this thread to download it (or if you're soompier, most of the time, you'll see it in there too.)
Yes, but only episode 3, 6 and last episode. These hardsubbed episodes will be released first in WITH S2 Clubbox, and usually 2 days later the torrent will be up in d-addicts tracker.
