nope and nope
Now we're really off topic and you have some reading and testing to do... it's gonna take some of YOUR time...
For my defense, I did spend quite a bit of time on this (including going through the readme file and 2PAC thread) without succeeding.
I managed to have it work nicely on a batch file or command line, but not in a config file.
I want to go the config file way, mainly because I can't figure out how to set up multiple pool in a command line, which you can do in a config file.
My mistake actually was that I tried "suggest-diff" : 128 in the config file without the "" around "128" and cgminer does not like it...
Thanks for your help, and the explanation on the diff with the pool :-)
