A regional list of players looking for RBGs that would show up much like the current Looking for Raid *Other Raids* tab. This would not be an auto generated group and would just expand your reach past Trade Chat.
Players could list their character and add a note.
The UI would display
Name and Class
Current Rating
Highest Rank
Main Spec and Off Spec
Mic Yes/No
The list would allow cross realm invites with out real id.
