We are working in a rework of the pool that will include a (good) design, new payout algorithm (like suggested above) and more functions like normal pools. Keep tuned.
In the meanwhile you can feel safe mining here, your coins need to get 120 confirms before they are available. We have under 0.5% of stale shares and we have solved more than 500 blocks already! You will not lose any submitted share, it will be credited instantly to your account after finding a block. Miners of any hashrate are welcome in our pool!
