We have a couple of new URLs to help show efficiency.http://bitcoinpool.com/cgi-bin/checkeff.cgi
This will show everyone who has done something in the current round.http://bitcoinpool.com/cgi-bin/checkgoodeff.cgi
This will show people that are above 50% efficiency.http://bitcoinpool.com/cgi-bin/checkbadeff.cgi
This will show people that are below 50% efficiency.
Anyone on the following list: http://bitcoinpool.com/cgi-bin/checkbadeff.cgi?30
is below 30% Efficiency. Either fix this, or your account will probably be banned (again in some cases).
