Yes.  It helps to pay nastyfans.org server costs.  While we charge 0% fees to miners, we also use merged mining to generate altcoins for server costs (and hopefully one day regular lottery prizes).  Merged mining is extremely popular these days though, so you need quite a bit of hashrate to mine any altcoins due to the solo-mining nature of merged mining.



Currently, there is no benefit to mining as a "member."  We had the recent contest where you had to be a member in order to enter, but that was the first time there was a benefit.  Even non-members have their mining information tracked by their Bitcoin address and should they choose to become a member and register their address at nastyfans.org down the line, they will get lottery tickets for their accepted P2Pool shares.



There isn't really a way to mine "as a member" at the moment.  You can use your nastyfans.org username to link your hashes to your member account for tracking purposes, but that was only beneficial during the lottery period.  Any hashes submitted using anything other than a Bitcoin address as a username are donated to the NastyFans address and not the miner.
