CiviCRM Community Forums (archive)

I'm trying to figure out where and how I can add data to a contact's activities (not add an additional activity)
On the activity page there is a table that lists emails for example with some info about it, how could I extend that table to include some additional info. Is a core modification necessary or can that also be hooked into (didn't get that from what I've been reading).

When you view contacts (e.g go to Contact Search and just hit search), you will come to this page: /civicrm/contact/view?reset=1&cid=2 (or something similar).

At the top you have the tabs: "Summary, Payments, Pledges, Membershipts, Events, Activities,...,..."
Under the activities tab you have a table with the headings:

Type, Subject, Added By...,... I want to add another column here and associate a custom query with that tab (well not custom but a query that is used somewhere else).
