Someone other than 07jjackson has created a user page
with that name
containing the following:
[cut]
Does this user exist? Should the page be deleted?
The user does exist in the sense that it appears on [[Special:Listusers]],
which (developer please confirm) means that the login account was created.
OTOH, the account has made no contributions.
I'd leave a note on the talk page of the creator of the page,
but we might as well keep it for now.
