Gnome bittorrent downloader

Hi I am very new to Linux and file sharing etc-so need replies in 'plain English' as far as possible! I have Gnome bittorrent downloader but it is taking up too much bandwidth (I am sharing the internet connection so this is the source of a bit of consternation...) You can easily cap and alter the uploads and the upload rate on the display screen, but not the download or download rate, does anyone know if this is possible? If not is there another bittorrent client with this function that is very easy to use/install/ is stable?
Thanks, Emily

PS I use linux fedora

Azureus is one of the best bittorrent clients out there, and is available on many platforms, including Linux. I know it has the ability to cap upload and download speeds.
