Thanks for all your thoughts. It happened to me again today but this time there was a sizeable list of other "Favourite artists"...not just me, which is reasuring. Karen,  what you say is totally logical and most probably the main reason. I have a friend who I managed to talk into signing  up here, but as yet has still to post anything, she's worried of not being good enough etc.  Shame because more often than not a few positive comments is enough to encourage you to post some more.....and before long your hooked!
