Just a thought – if you're bing taken to the BT Yahoo page then try signing in there with your BT Yahoo user name and password which will be the same as the one you use on the UPT group. If you are still a member of the UPT group you should be able to go straight in then. I'm not getting taken to the BT page but them I'm permanently signed in (for 2 weeks at a time anyway) as I use Yahoo e-mail as one of my main addresses. There have been "issues" with Yahoo and stolen passwords. They tried to get everyone to update their passwords but so far it still accepting my old one as I haven't bothered. Just possible if you're not a regular on Yahoo groups or e-mail that Yahoo may have deleted your account. Yahoo has a habit of following the least user friendly line that it can – especially since they got the new CEO.
