My tree has about 10 instances of eGuidePublicUser ... one with no
numbers after it and then another 9 with five digit numbers listed
after "eGuidePublicUser"... the first 4 having an underscore _ between
the eGuidePublicUser portion and the number behind it... the last 5
(larger numbers) don't...

Two of these accounts have "last login date" set -- the others don't.

Any idea how I can tell which of these are unnecessary without
breaking things? :)
