Please forgive my intrusion and my beginner questions.  If I have posted in the wrong section please do point me to the right place.

I have a few questions about mining bible pay.

I have 6 linux servers and 1 windows machine I was using to mine. I have read alittle up on all this to at least get started and know how to stop start the mining process.

1. Poolinfo says unable to sign cpid for all of my servers. What does that mean?

2. Do I need a worker for each server? Or is 1 worker for all the servers good?

3. This was all working and then suddenly I was no longer on the leader board and all my machines were not really doing anything?  I didnt change anything. Is there something that needs to be updated daily?

4. Is there a cluster form or something i need to cluster all my machines together to get more bang for the buck?

5.  After retrieving the coins then what do i do with them?

6. Is their a way to list all the machines that biblepay see's working.  I have 7 machines but the leaderboard says 3.  I have 4 machines coming from the same ip address and 3 servers that have a different ip address.

Thanks,
