The link is on the MW forums, one of the stickys at the top of the number crunching forum and the preferences can be done via your account on the web site for each project Toxic. You can check your settings by just kicking off a request for work and the priorities will update straight away. Im not sure about not crunching seti on the cpu and milkyway only the cpu, Id imagine that it would be the dreaded app_info again or another xml file. Id be interested in finding out a way to do this as I have been thinking along the same lines myself, want to support Mr Halz in his endeavours to get the MW team up and running
