How do I say in one breath that I think it's a great idea ... even though sadly in my case there isn't a cat's chance? I was going to say that the first thing that came to mind was a marathon-related rec - i.e. Georgina Kirrin/jessinengland's Cards on the Table set, and then I saw that I wasn't the first person to think of that! *g* (which entirely coincidentally I re-read today, very shortly before seeing your post).
Anyway thank you for posting a lovely idea, and I hope people are in the right meat-and-headspace to do stuff!
