OK Harriet says she would try to log on later and follow up on some of those she didn't get around to.
Thanks for comments/suggestions on the webchat process - we do suggest that guests prepare some answers in advance, and during the chat we try to highlight emerging themes/topics - we don't like to be too bossy about exactly how guests do things because we're conscious they're giving their time to us, often out of pretty busy schedules, and MN webchats aren't (yet) compulsory
but we will have a think about how we might be able to help future guests on busy chats get through a few more questions.
