Thanks for all the positive input. This thread should have run out off steam a long time ago ( some may say it should never have been started in the first place, so to you, apologies ; ....). It's served its purpose as an enquiry re. my ongoing psych quest. This site is a very broad church indeed, and all the better for it. The overwhelming majority of contributions are informative, intelligent, amusing, and above all, friendly. I would like to ask that we let this thread die now, and don't add to it anymore. I don't want to lock it (for obvious reasons) but I would like to see it ended. Thanks.
