Tx u for the torrent and giving me a chance to view asian film with english translation. Sorry to hear about your personal reason and good luck on your endeavors.
With regard on what to do, it is simple. Torrent to other big name site for torrent to be around for a long time. The key is seeding (seeding box). So keep seeding and keep up the good work of translating. Sometime, to save on bandwidth, it good to use an effiicient format (cannot recall but I think it is rmdb or mkv, just g00ggll33). Also, consider zip or 7zip the file and if the compression is beneficial then consider uploading in that format or zip. Now, if we have a big series then we can zip multiple of 10 (ie 1-10, 11-20, etc = to have totalfile/10 subfiles to make the series ) rather than one big giant file.
Again, money is not the answer. Just love for asian movies, translation, and lot of seeders to keep it alive. tx
