When I try to get to my groups, I have to sign in, then I'm sent to some Yahoo! home page with nonsense articles and absolutely no way to get to my groups. I don't know if this is a mobile-only problem, but it's frustrating - especially if I've just followed an email link to a group I manage. If you can't work it to send a person to the page they expect to land on, can you at least make it possible to get to my group? Maybe a link near the top, 'See my groups' or something?
