here you find how you can join??
if you ever wondered what it would be like without pool bosses and ever wondered what it would be like what would happen if the pool went down
here is the answer
normal pool go's down you lose money because you switch to a backup pool.
p2pool if a node go's down (and you have set youre backups also on other p2pool nodes) then you will not lose money.
reason for this is that p2pool is a global pool and works not as a normal pool
p2pool uses nodes for the miners to connect directly
this means if a block gets found there is nothing inbetween you and youre btc.
so no scam pool boss or other people
WIN WIN if you ask me
other thing is that it is ddos safe at all times when you set youre backups also on other p2pool nodes.
and its hopper proof this means the longer you stay the more you make (takes about 24 hours for a miner to settle in very good)
well let me know what you think or if you need more info let me know
