Does adding hash power to this pool change things for you (for example I point my miners at the pool)
It helps a little. We use altcoins from merged mining to pay our server costs and keep the pool/website running with 0% fees. Merged mining has become so popular that we rarely see any altcoins though. Hopefully that changes as we grow and we are able to generate an excess of altcoins that can be used for cool incentive programs like the lottery.
How often do miners get paid out?
Currently, miners are paid out each time P2Pool solves a block. This typically ranges from 12-36 hours depending on the hashrate of the P2Pool network. We are looking into implementing a PPS payment system that will steady payments for those who aren't comfortable with variance. That way you can see your earnings and feel comfortable during long P2Pool rounds. It may also be worth noting that P2Pool is slow to start paying out new miners (to fight pool jumpers), so please give it a few days for your payments to normalize before getting frustrated. The plus side is that you typically continue getting payments for a day or so after you stop mining on the pool, so it balances out.
I don't quite understand the P2Pool concept and how it differs from other mining pools... can someone explain?
THIS explains it better than I ever could. The simple explanation from me would be that it is a decentralized pool that works on open source software. Which means there isn't 1 person in charge of the pool potentially using miner's hashrate maliciously. Sort of like how Bitcoin works in contrast to Mastercard.
If I point my miners to the pool will I need to purchase a seat at some point? I ask because the website says I need to within 30 days or my account will be deleted...
It is not a requirement for you to be a NastyFan in order to use NastyPool. Anyone can mine with us, so long as you use your Bitcoin address as your username. However, if you want credit for the P2Pool shares that will eventually be used in a lottery incentive program, you will need to have at least 1 NastyFans seat (and eventually you will have to sign the Bitcoin address you are using as your username on the pool, so that we can properly credit your account when the lottery incentive program goes live). It is correct that if no seat is purchased after 30 days of signing up, your account is considered inactive and is removed (we only want to track signups for active users).
what do you get if you win the lottery? and how often is the lottery run?
Right now we run lotteries whenever we feel it might be fun. Celebrating a 2-year anniversary currently fit that bill. I am still in discussions with nonnakip about the details of an ongoing lottery. We originally thought this would be a great way to pay out our altcoins that are merge mined, but there are other things we may be able to offer as well. Basically, the more popular the pool, the better the lottery will be. At this time we aren't generating enough additional altcoins to offer much of anything, which is why this last lottery prize was supplied by myself personally to try and bring some awareness to NastyPool as we begin working towards rolling out new and exclusive pool features.
is this pool run on a server or someones home PC? (sorry have to ask)
It is run on a dedicated server.
Im sure I will have more questions but this is a good start.
I love questions. Keep 'em coming.
