personally think they are a waste of time mate the only good feature i found with them was the resume download ability if you got disconnected from your dial up,but that is really not an issue for those on anything other than dial up,(for standard downloads that is).same applies to winmx so called accelerators,you will not increase the number of sources you find by using an eccelerator,p2p is just that peer to peer,the number of sources you find is dependent on the number of people using winmx at the time,nothing will increase this volume unless more people are using it.same goes for download speeds your best bet is look through the search results and look for those on fast connections which will obviously be able to upload to you quicker.
