"Contacts" ... And your efforts in this forum are deeply appreciated

I have office 2007 (12.0.4518.1014) part of MS Office Ultimate 20076. I very
recently noted that I have some how duplicated certain items under My
Contacts. I had a grouping of contacts called just "Contacts" and another
called "CEO"

Somehow I noted that today I have "Contacts in Personal Folders" and "CEO in
Personal Folders"

I do not have a clue as to how these two additional grouping were formed.
Can anyone help out here. They are not identical in content

By the way, I seldom see any comments here about what a great job you guys
and gals are doing in supporting ths forum. I for one am deeply
appreciative. More than I can count you have helped me out of a pinch. When
ever something goes wrong or doesn't look right you folks usually have the
answer. Please accept my personal words of appreciation. While most of us
know you are strictly volunteers, I sometimes wonder if some think you are
paid for your time.

Muchas Gracias

Jerry
