[ic] address book: delete & expand fields

[interchange-users@icdevgroup.org (Andrei Gologan)]

I need some help, i allready posted this, but no help until now ...

it is about  the column address_book inside the userdb table. I need to
expand the column address_book inside the table. The column holds following
fields (taken form interchange database documentation):

s_nickname
  name
  fname
  lname
  address
  address1
  address2
  address3
  city
  state
  zip
  country
  phone_day
  mv_shipmode

it looks anyway that the documentation is behind th code, (company is
allready in there) but i still need some extra fields.

and here I need the extra fields company, company2 phone_night. I looked
everywhere but i dont get where the definition for this column is stored.
the column holds data as follows:

{'andrei' => {'state' => "Hessen",'country' => "DE",'address1' =>
"teststr",'address2' => "123113",'mv_data_fields' => "username company fname
lname address1 address2 city state zip country phone_day",'city' =>
"test",'phone_day' => "000000000",'lname' => "lastnametest",'fname' =>
"hallo",'zip' => "87954",'company' => "Testing ag",}

Where should I look, where can I do it ?

Thank you !!

Andrei
