I'm new here and apparently don't have the login procedure
I see the (expected) 'welcome' screen and my login appears to be recorded, but when I post a new message, it ends up having been posted by "Anonymous Monk" rather than by my login name.
The other curious thing is that my login name appears for a while in the "Other Users" list, but then in a few minutes it disappears from the list.
There must be some obvious thing that I'm missing about how to log in correctly. Advice appreciated, including by e-mail if you'd prefer.
