ok, I got that. But why is the address not showing in the pool Graphs?
It's showing there, on another node of the network
http://mine.fairquark.com:8372/static/graphs.html?DayP2Pool are a little different, what you connect your miner to is a "node", and the nodes interconnect each other using P2P (hence the P2Pool), and they form a network that mine together (for more details see
https://en.bitcoin.it/wiki/P2Pool).
Currently the main P2Pool "network" for FairQuark is comprised of 5 nodes, for instance if you look at
http://fairpool.co.vu:9640/static/index.html you'll see 4 peers (1 in 3 out), the "pool rate" is the total rate of all 5 nodes and the "local rate" is the rate of miners connected to just that node.
