Having started looking at private trackers I've realised I need a seedbox. To date my ratio on u-torrent is 0.7 (lousy I know) but this is largely because I download a lot from usenet while I'm at work which fills up the HD. Even though I have u-torrent running in the background almost 24/7 I find myself removing seeds to free up space on the HD. Anyway.... I have been googling seedboxes and have a few questions.
If using a seedbox does my U-torrent ratio still matter?
I read that a seed box always has a 1+ ratio. Is this because you upload files to the seedbox so in effect you are seeding from word go? Someone mentioned leeching with seedboxes. How can this be yet still always have a 1+ ratio?
Sorry if the questions are so basic.

Thanks
