Sites under Blender group

I heard but not sure this is correct or not that BlenderArtist CGCookie BlenderCookie Blendswap -these websites are under same group that is Blender Community. So as Iā€™m a member of BlenderArtists, Do I need to create different accounts for CGCookie and Blendercookie and blendswap? Or This account covers all? :stuck_out_tongue: :confused:

Blendswap is not part of CGCookie
I believe currently a separate account login is required for blenderartists than for the other CGCookie sites
