What happened to the WCC? Just found this rating list below while looking for other items.
I vaguely remember hearing about WCC.
What happened to them? All I find now for WCC is 'world chess championship'.
Apparently they both rated top players.

Combined Top 100 - January 1999 FIDE and WCC Chess Rating Lists
Note: The 1999 FIDE World Chess rating came late and contained errors. This is the fourth and presumably the final version of the FIDE top 100 list.

The WCC was the "World Chess Council".

It was formed in 1998 by Kasparov after the collapse of the PCA (Professional Chess Association) in 1995. It was Kasparov's fourth attempt at an organization separate from FIDE.

It organized the candidates match between Kramnik and Shirov in 1998, which Shirov surprisingly won (5.5-3.5), and he was slated to play Kasparov for the title. The match never happened since the organization collapsed during the negotiations when the organization lost its sponsors, and folded.

The best detailing of the events of that time that I have found can be found here. (Note that this outstanding site has many more pages of history, so click the "next" and "previous" buttons at the bottom to read more. I would love to just cut-and-paste it, but it is copyrighted material, so you will have to go visit the site.)

You can also find a little information here.
