Hello mate,
Question One:
Is there a cap on number of torrents?There is no cap on computers in general. You change the max in utorrent settings / configuration. I have seen thousands of torrents in one client. Dont recommend it though lol... Max 300 is usually a good rule on a decent server / computer.
Question Two:
Error: File exceeds filesystem size limit?What filesystem do you use on the disc its downloaded to? NTFS or FAT? FAT is max 4 GB files.
Question Three:
Should I just get a seed box for everything?Personally I see it as a good solution for many reasons. Good speeds, good upload ratio, 24/7 seeding, anonymous downloading etc etc...
