Why did the pool fee go from 0.5% to 2%?

Had to upgrade the VPS its hosted on to handle all you Jims. Anyone can solo mine or make another pool if you feel its too high.

When will we be able to have even more Jim in our lives?

What is Jim? I don't know what you mentioned. Is it related to the project?

We are all Jim, Jim.

I've made some adjustments to the difficulty targeting, you should all be getting shares more consistently now.
