I've been searching around for a couple hours now looking for an online statistics/match panel for HL1 servers. Specifically something I could use for my pick up game players to login to and see stats/leave comments, see matches and on-going scores throughout 5 other servers linked to that database.
It's a huge system and I doubt it's out there for 1.6 but worth a try. I only know 1 community which is based in SA that runs a system like that with an online webpage login through STEAM that connects multiple pug servers of theirs and allows all users to login through steam through a web client to see weekly leaderboards, top players, weapon stats, and live server stats.
