Well done Bernie - it was on my to-do list to ask Linda, but I hadn't got around to it yet, so thanks for seizing the initiative.
Since Linda is already a forum member this is easy to set up. First, agree on a suitable time and date with her. It's best to pick a time when there are usually quite a few people active on the site, so evenings are better than daytimes, and perhaps a midweek evening rather than a weekend. Then make sure we all know the details and have the date firmly in our diaries, and one of us will set up the thread for the discussion to start a day or so before the agreed time. This will allow people who can't make it "live" to post some advance questions, and Linda can then get started on answering those and chatting live to everyone else as soon as the chat officially starts.
Does that cover everything? If not, let us know.
