To make a challenge request, simply put who you are and when you would like a challenge to start in the title. [e.g. "The Legion looking for a challenge to start immediately!" or "The Legion is looking for a challenge to start in late August]
Once your request has been filled, mark the title as "closed" or "filled" so that the CDs can move it to archived. Then when you want another war, start a new thread! If a request is left open for too long or starts to take on a life of its own it will be locked and moved to archived. Let's keep 'em current.
Most importantly, everyone have fun!
