Looking for slow miner shares

I created a mining script to run on my slow computer just for kicks. I've yet to find or submit any shares to the pool, but my setup is constantly busy receiving tasks and hashing. Can anyone point me to a solo mining pool where I can tweak the difficulty and actually manage to find shares while running at 3 MH/s? Also, if I never submit a share to a pool but somehow hit the jackpot and find a block, do I miss out on the reward?

First of all, i would recommend you to read BITCOIN MINING INTRO & RULES OF THIS SUBFORUM - READ BEFORE POSTING. Check https://web.public-pool.io/. Yes, you don't get any reward when you never submit any share. If you read his post more carefully, you would notice that post actually summarize your thread.
