You can get eMule here:
http://prdownloads.sourceforge.net/emul ... taller.exe
Once installed you can select 15+ downloads at once, in installation preferences.
Once running you can press the "Connect" Tab.
Once connected to a server you can click on an eMule link.
For eMule to work effectively ~40+ downloads at once can be selected. You can then configure eMule via options to decide how much bandwidth it uses.
If you have any trouble just post here, Good Luck!
