Hello everyone, and thanks in advance for replies!

Im new to mining, and I've started mining with my Lenovo laptop and my "home built" AMD PC.
I registered on the slush pool, but I dont think my setup is quite right.
Can you please help me figure out what I'm doing wrong?

Question 2:

Does 1 worker have to be 1pcs of hardware? So that 1 worker is one PC, and another PC is 1 worker?
Or can one worker be 1 hardware (antminer, BFL product example), so that you can have many workers on only 1 PC?


Question 3:
What do you advice me to purchase as I am new to mining?
I'm currently considering the: Bitcoin miner 7.8 GH/s BFL Jalapeno fra Butterfly Labs
Is that a good option for me?

Thanks in advance,
Magnus Norway
