Hello msy2008,

TreasureQuarry's Infinitecoin pool is currently unavailable - people stopped using it quite some time ago when the Infinitecoin network's block rewards dropped, so I stopped the Infinitecoin pool from running without users to conserve server resources for use on the other pools like Litecoin and Dash.  If there was enough interest I could possibly consider getting the Infinitecoin back up and running in the future.
