The 23/5/09 Raid is a Raid, engineered by the Penguin Pranksters and joined by RITARO, and maybe Anonymous. It is plotted to be similar to, but superior to the 2/2/09 Raid. It is planned to be almost the same, except there will be more members of Anonymous and more pre-testing of the limits of moderation. Another feature of the raids is that there will be more forum raiding.
The CP Raider Alliance is also looking for allies in it's quest.
