Forum:Referencing personnal messages

Hello. I recently reported to 343I Grimbrother One what I thought was an error in the Waypoint's encyclopedia, and he replied with a Halo trivia about Pelicans. But I don't know how I could reference this in-article whithout being erased for possible fake content. Is there any policy about this ?

 * I suppose that would count as a letter of canon. Sith-venator Wavingstrider Fett helmet.jpg ( Commlink ) 16:30, 21 January 2015 (EST)
