Just supporting those who have complained, I have been lecturing in Computer Science for 14 years and that includes web site design, as well as helping small companies set up web sites and I too am having a great deal of trouble with this site.
In spite of reassurances, I have had to reset my password to get in. I did not expect to see old posts but I did expect my buddies and messages to come across and I have now lost contact with some as my cognitive challenges mean I have real problems remembering names and user names are particularly difficult.
For those who designed, I am aware that you have put in a great deal oif hard work but it you must remember that development without involving the user is fraught with major difficulties and unlikely to lead to user acceptance. There is also such a thing as user testing.
Oh well nothing remains the same eh!
