1. Start making Statues two days before the FA begins.
2. Start Blacksmiths and Necklaces a day before. (Remind people not to "collect" them until the FA begins.)
Make as many as possible. You won't know how many you need until the maps go up, but it'll never be enough.
3. Have a coordinator, someone who tracks what's been made and what's been played. The coordinator should chart the entire map, all 24 waypoints, to know what's coming up. (I'm coordinator for my FS.) And then make all the long-lead stuff you'll need first -- and make more than you need because you never know who's going to be on line when the item comes up. For that same reason, don't assign specific builds to specific players, you want as many making one thing as possible.
4. I put up a message each evening about midnight detailing status of the FA, what path we're on, what's still needed. Not everyone can see the message board, so an abbreviated version goes on chat.
5. I avoid chat for major strategy and messages because it gets so cluttered and such missives get lost. But it's great for "need three more carpenters on Blue #6" or "I need 100 planks for a wand."
6. Have everyone build as many Level 1 Workshops and Tier-1 Factories as they can find room for. I like at least 20 workshops, 5 of each factory, but if someone can cram in more do it!
7. Discourage using time boosts and diamonds until the third level. And then a good use is for spells if needed.
8. Don't overlook Help rounds and the Tournament as sources of spells. If you have a good active FS, getting trades for the goods needed should be easy. A request on chat should get a quick response.
9. Encourage newbies. For them delivering one or two of something is as big an effort as delivering a dozen or more for your top-level members.
10. Remember, this is the one Elvenar activity that really needs teamwork. Even if yours is a "casual" FS (i.e. not one of those 10-chests groups) you can still get people excited about the Adventure.
