Release of Starcraft 2 seems to have dramatically decreased Sins activity :-(

Sins Forums
I am sad to report that the release of Starcraft 2 seems to have reduced Sins online player counts by about 40%, as predicted. A small group of fiercly loyal Sins fans continues to play 5v5s on Diplomacy, though. Hopefully some former regulars will tire of the clickfest and long for a non-clickfest RTS.
