This is a first for me. I joined Dididave.com less than 2 weeks ago. I had 2 torrents that I downloaded and was seeding for a few days after completion. They were at 1.0 and 1.3. I tried to download a torrent (not start it mind you, just download the torrent) and it wouldn't let me stating that I have too many active torrents! So I removed the 2 torrents that I was sharing and tried to download again and this time it let me do it.
So much for trying to share! Diddave gives you like 4GB UL to start with so it wasn't a ration thing at all. In fact my ratio is 7.237. Go figure.
