The Speaker of Flame is essentially the individual tasked with running the event. They are given a set number of duties and they conduct it accordingly.
There's a lot of OOC communication involved however. Maekrux (Kaerisk) and I spoke back and forth with one another in order to keep the event flowing smoothly. This gave a broad idea on how one -can- run it, though they have leg room to wiggle in a touch of their own - speech being a good example for this.
In the end, Kaerisk is the one that organized the event in its entirety, though he gave the position of power to the player and character that was chosen as the speaker. Generally, a thread is opened before the event takes place (probably a few weeks in order to work out time schedules) and someone from the community is nominated.
