Initiates a raid ready check. Can only be called by the raid leader, does nothing if called by other raid members or outside of a raid. As of one of the 2.0 patches, this function can also be called while in a normal party, but again only by the Group Leader
- This function initiates a raid ready check and will cause all raid members to receive a READY_CHECK event. Processing of the ready check results appear to be either server-side or internal to the client and do not seem to be directly available to the scripting sytem. The results are reported via a CHAT_MSG. Please update this description if you learn more about this mechanism.
