Dear Kim It is difficult to diagnose the problem, and clearly you have succeeded in posting this message. There is an automatic timed logout, and I wonder if that is what has happened to you. Typing does not register as activity, and many people have been caught out by over-running their time while they are actually composing a message, only to have it rejected when they press 'post'. Might this be the case?? If this is happening, it may be worth logging in and then using the back button. Your typed message may be retrievable. Moderating team
