Re: "Why is Pool Hopping a Problem?" - If you use a PROPORTIONAL pool, read this!
Switch pools to one which uses cheat proof scoring and tell your friends to do the same? You are welcome at Mainframe and 1% k goes back to the community developers and not in my pocket. Its for a good cause! 
Just registered, but: Pool Hash Rate 0.000 Ghash/s
What's up with that? As it seems, the pool only has 4 members (including me), but no one is mining? heh
Also, where do I see how many fees I've got to pay or if there are fees on payouts?
What options do I have? Only the "start hopping yourself" one?
That is one option.
Or are there some kind of programs for that?
The other, much simpler (yet less profitable) option is to switch to a pool with a fair reward system. Eligius comes to mind, and eligius has very low variance as well (that means: steady income).
I've read that a lot of people are happy with eligius, so I might give that one a try. Thanks for the replies so far
