Melix is right that Proctethia does RMB awards every month. However, you might be thinking of the Rejected Realm's weekly RMB awards. You can find the most recent TRR RMB awards here, to get an idea if that's what you're looking for:
Welcome to the Rejected Realms' Regional Message Board Awards! The winners will be announced biweekly, and the data collected will be from a two week period (from Thursday to Thursday).
