Hi there, I wanted to test if this posting would work, and figure this is an appropriate posting to respond to. I had experienced no difficulty in posting to the knee1 web-site, under two different e-mail accounts (both now dead), but have had difficulty with third e-mail account. I did send reports with error messages to knee1 but received no response (couple of months ago). Now re-trying to post so that I can respond to people experiencing knee difficulties. I have re-done my log-in details, and hope this will now work. (If it does this message is redundant; if it doesn't it doesn't matter because noone will read it!!) Hope you have no further computer problems. Liana.
