On second thoughts, I won't report the indicated problem in PAF. That's because PAF has disappeared into thin air.
For details, without the name:
I shall call the user "xxx". When I look up "xxx", it shows that name as an alias. When I check the profile, it says:
The user ID nnnn does not exist.
where nnnn is the actual user number.
Looking up under Board Central also says that the user does not exist.
His email indicated that he has created another account. He is having difficulty logging into that. I suspect the problem in this case is in his browser, rather than at the site. I was able to login as this alternate member.
Incidently, the profile information no longer has a visible password. So how does an administrator help a person who is having password problems, and can't get mail from the site that tells him the password. (Note, this is a hypothetical, since it isn't the problem in this particular case).
