I’ve configured HLstatsX Community Edition to gather stats on how people are doing on the three Left 4 Dead servers that I run. I’ve made sure that all the annoying popup messages are disabled so you don’t get spammed during the game, though I’ve left the join messages enabled which show others your ranking when you join. Enjoy!
Update: I’ve had to disable this for now. Sorry folks!
Update 2: I’ve re-enabled HLstatsX now.
