When the forum came back I was already logged in on my iPad.
Not so with my PC and I can't log in. I know my username and password but "new" software calls them invalid. Just in case the "forgot password" system doesn't work as it returns "page not found."
I'm afraid to sign off on iPad to see if I can then sign on on PC, but it shouldn't be this way in any event.
More work to do?
