e-mules uses credit based UL/DL stat. You can reduce your UL's but at the same time you will be
limiting your DL speed. E-mule is still by far one of the healthest P2P networks there is. There are modded versions laying around, but really being a leech is a really lame thing to do, as it siphens the life out of the network. EG: if we all leeched there would be no network, and we all loose.

. Also 90% of the time you will be filtered out by newer versions, and will find yourself getting lower and lower Kbs, as u get banned continiously.
Try picking up a better DSL plan, go for unlim UL/DL's with TPG or one of the other alternate ISP's.
Ive used e-mule for about the last 3 year's now. Just take the attidtude, it's slow, but hey you get want your looking for.
