Using countify to determine who voted

For the trustee elections, it's important to have a record of who
voted because it is by voting that one becomes a member of the
Gentoo Foundation. Any election official, after countify --collect
has been run, can determine that list using the following one-liner:

while read num user; do grep -q "confirmation $num"
master-trustees2005 || continue; echo $user >> voted;
done < confs-trustees200

That's what we used to determine the existing Foundation members from the
2005 trustee election.
