So assuming we don't hear from the GM how long do people want me to wait before making the OOC?

Note, I'm not volunteering to take over as GM or run the RP. My experience with fire emblem is limited to 9 and 10, but I do at least want people to start planning how the RP will work and be making their characters, and in that time I imagine we can elect a new GM if the old ones don't show.
