People interested to see the old matches, they are still there, and can be found via search-button, advanced search, search term "chess".
When I use the simple search via the default popup window and enter "chess", I strangely do not get a single result, though.
Usually all match threads were marked with "CHESS MATCH X vs. Y" in the headline.
We had a spike in activity in May-September 2006, I think, and last year again. I still remember my two matches against Scandium 2006, my toughest opponent so far.
