I'd like to be able to configure what shows up in the report. For instance, here is what I see today:

BUILD_USER_LAST_NAME: Smith
Requester: Bob
BUILD_USER_FIRST_NAME: Robert
BUILD_USER: Robert Smith
SVN_BRANCH: misc_updates_to_stuff
BUILD_USER_ID: robert_smith

Requester is a manual field that our users input because when they are in the queue, we don't know who initiated the build. By having them input the value, we can see who has a build in the queue.

For the other user params, they are showing up from the plugin: http://wiki.jenkins-ci.org/display/JENKINS/Build+User+Vars+Plugin

It's rather annoying to see the user's name show up that many times.
