I did it the same way icy lettuce did it and it works great for me. He may have forgotten to Save and Restart at the right points and defaulted to sgminer. I had a VertMiner.conf but Mum 3.01 said that was a no-no and renamed it. I just converted to a command line format and defined my pools in Add Coin. It switches and mines great.
Woolls yer awesome

Glad to hear it's working! Good reports all around from most folks. I have a few small fixes in store for a 3.0.2 release, and then 3.1 will add Keccak support along with potentially faster (but only if GPL compliant) X11 miners.
