CM Team has several scenario write-ups ready. Community Votes on the Title/Topic. Scenario Write-up is issued to community immediately after vote concludes. After a week, CO's may be selected allowing time to decide if they want to, and if they can assemble a team they feel strong about. If Multiple CO requests, we do a simple lottery with an RNG. Once CO's are selected, if there are ANY concerns, they may then bring them up to the CM heading the event (Who, by the way, would be in a role of coordination, not aviation for the event). No changes will be made without getting input from the community unless it is a game altering flaw. Allow a week. The Teams will have enough to start planning while they wait for this process, so no time is lost.
Do this twice a year. MAYBE 3 times since the write-ups are already there. We don't need more, nor is there adequate time.
Those choices, A and B, are black and white, then you gave C as a suicide pill.
