Oh, dear. Was that too geeky? Sometimes it is difficult to answer questions (and ask them too) as we are limited by the size of the post-it notes. I am a library Answer Wall so I have taken on some of the characteristics of my library friends: for some questions I would really like to sit down (alas something I cannot do) and have a conversation with you so I really understand what information you are looking for. With limited and/or unclear information I do the best I can, but do on occasion miss the mark. Please do keep responding until we get it right though. I do want to help and I do want to provide the information you need!
