There is no minimal speed limit in the pool. What miner do you use ? Have you found a share already ? How long you are mining ? PM me your login name and i'll check my logs.
Speak of the devil. One of my threads just had a hit. Now I'm up to 10.14 MH/s. I guess I'm okay.
(I'm using jgarzik's CPU miner on two different dual-core boxes I have.)
I made an account earlier today, and I'm still reading 0.00 MH/s for my hashes. I'm throwing 4 CPUs at this. (My GPU's apparently don't support OpenCL.) I'm reading "0.00 MH/s" even though my threads should be giving me at least 1 MH/s.
