If there’s a way to log out of the forum, I haven’t found it. Normally this is something that I would feel no need to do, but today I have a good reason.
Six years ago I established my forum account. Yesterday, when I needed it desperately, the login failed. All attempts to recover or reset the password also failed. So I created a new account, and used that to get my problem solved. Now I’d like to prove that my original account is really defunct, but I can’t log out of this one to log in again!
OK, I’m updating this posting in lieu of a reply, which I would normally be forced to wait 7 hours to make. Thanks for the hints. I can only say that the functionality is well-hidden.
Note that I’ve logged into my original account many times since the switch to this new forum.
