hi What am I doing wrong,currently 50 % of the replies I have made to readers questions have failed,a few days ago,i logged on .answered two questions without problem then typed in another answer and the message came up please log in,so my effort in typing was wasted as when you log in your answer just disappears ,is there a log on time limit ? .today I logged on ,read somebody had a problem,typed an answer and again message appears please log on and again my effort wasted.not worth the bother.
