Tol-in-Gaurhoth XXI: Dueling Wizards Werewolf

[Lalaith]

Morm, the rules seem quite categorical:

The werewolves do not know each other's identity because while they are werewolves at Night, they cannot detect the identities underlying the curses

Also:

Note: Werewolves do not PM each other and therefore cannot debate with each other; thus, they are not going to find out each others' identities

Even if the EW were allowed to communicate wolvish identities to his pack via the sub-mod, as spawn points out, it would be dangerous for him to do so.
