first post anyway, i was downloading the beginner lessons torrent file. may i ask what's the difference in the informal lessons? and is it just me or is it that now you need to be a member to download the torrent files?
The informal torrents contain informal versions of the corresponding lessons' dialog. They contain only the dialog, not the entire lesson. They're also available from each lesson's page and in the Learning Center.
You don't have to be a subscriber to use the torrents. They're just kind of iffy right now.
