How to Change a GROUP to a USER???

I seem to have messed something up and hope someone can get me out of a
jam.

While running the latest Tiger, I used Migration Manager to move an
existing user from another Mac to my own Mac. So, my Mac now
successfully has three individual user accounts on it...the two that
were already there and the new moved one.

Then I updated my Mac to Leopard. The update worked fine (but see
below) and I updated that through Software Update to the latest
Leopard.

But, I notice that now when the Mac boots up, it only offers me the
choice to log on to my two original user accounts. The recently added
account does NOT show up in the log in list.

I've since discovered (using the User System Preference Control Panel)
that the user that was missing is now considered a Group! I don't
understand this. I didn't import a group using Migration Manager, I
"migrated" an individual user account and it showed up fine in Tiger.
But, now it's a group in Leopard...apparently a group with one member,
itself??

I had three users with Tiger, but with Leopard, I have two users and a
group. The new user's files are still apparently correctly named in the
Users folder, but I can't log in to a group.

How can I fix this up? Can I change a Group with one member into a
single User? I might be able to delete the group, and re-use Migration
Manager with the other machine, but I'd much prefer if I can just fix
things up without re-migration.

Any ideas appreciated...

Users created on Panther and Tiger are set up with their own private
group. For example, if I created an account "fred" then the system would
also create a group "fred" with that user as the only member.

Users created on Leopard, and on Jaguar or earlier are set up to be in
the shared group "staff".

It sounds like Migration Assistant has somehow managed to migrate the
group for your third account but didn't create the user. I've never seen
it fail this way, so I imagine it was because there was something
abnormal about that account on the original system.

Since the home folder has been copied, it is probably easiest to fix
this by creating a new user and then replacing the home folder of the
new user with the migrated one. Doing this is a little tricky because
you may need to change file ownership for the home folder, or user ID
for the new user, to match the migrated folder.

I don't have time to go into detail at the moment.
