Thanks, Helen! I did download it, and look forward to digging into it.

I use "idea garden" from something someone said from back in my graphic facilitation days (I don't remember who). They talked about how often people, during brainstorming, will put stray ideas in a "parking lot" -- but nobody likes going to a parking lot! Instead they suggested putting those ideas in a "Garden" because that's where things like to grow, and people go there sometimes just to look at them.

The concept stayed with me, and I use it all the time. Thanks much for your suggestion!
