The Definition of a Freeloader thingy is on every single one of my posts, and in no way pointed at you and should not be associated with my reply. That is for everyone

It is possible to set your upload slots to 1

go to tools<options<uploads<slots and set both to one, in uploads you can choose basic and move the slider to the desired position

the sliders range will be affected by your setting in tools<options<speed
Choose whatever setting fits you best

Also you should adjust the download slider accordingly as I am sure thats part of your problem as well. You upload a request and download pages, off course sending e-mails you upload

Also dont have many downloads at a time if at low speed, because every single downloadrequest used up bandwidth as well

As an example I have 119 KB down and 28,5 to 31 KB up depending on time of day and I never have uploads set over 24 KB and never over 3 slots for it to not effect other activities

I also do not understand your 10 Mbps as they would be more than 9 times faster than mine. mine is called 1024/256 Kbps

If it's some kind of dsl you can google for a speedtest and get your speed in KB per second, which is how bandwidth is measured in Limewire, making it a lot easier to set

Hope this helps
