Hello,
in AfterShock you have the option to write clientstats AND serverstats. For clientstats look at the cg_autoaction cvar( bitmask for stats is 4 ), for serverstats use the g_writeStats cvar. For example we use the serverstats for the AfterShock
webpage with stats.
The AfterShock project really needs some wiki-writers i think
