I know this is far along in this thread, but maybe someone can help. I've read the readme yet it doesn't really state.
What does "rejected" imply? I am solo mining using CGminer. 3x 7950 running at around 500k/hash each. I've had it on perhaps 72 hours, so far I have had 4 rejected 0 accepted.
Rejected means that the work your miner did was redundant by the time it was submitted (i think).
Joining a pool should solve this problem.
