There is now a Facebook Ruby Ferguson group for discussion of all things Jill. It's been started by John Rees, and it's here. (And thanks for the link, to Vanessa from Fidra. I whipped it off her blog having been totally incapable of working out how to find it after John rang me to ask if I minded if he linked to the website).
Eek - I might actually have to join Facebook now. I have held off until now because I've heard how addictive it is and I know what I'm like, but can I resist the appeal of Jill? I don't think I can.
