how to safeguard voter registration lists in your local precinct(s)

i'm sure others have cited the citizens' election protection toolkit at http://www.blackboxvoting.org/toolkit-voter-registration.pdf, but if you haven't seen it yet, check it out.
here's a section on monitoring voter registration lists:

Here are some of the things to look for when checking voter registrations:
• Track the number of registrations up to the deadline for entering them into the system.

• Check to see that voters aren't purged after the deadlines. Purging of names on the basis of change of addresses should not occur any no later than 90 days before a primary or general election.

. . . .

• Spot-check some of the addresses in the database. Following your best hunches, spot-check whether they are residences. Google "maps" has a satellite option that allows you to enter an address and see a satellite photograph of the area, though it is not 100 percent accurate. If you spot addresses that appear to be vacant lots, or industrial areas, drive out and see for yourself.

. . . .


• "Caging" tactics: See if you notice evidence of a large number of purges in a specific demographic group or area. Some political parties undertake the expense of sending registered letters out, then urge the removal of any voter who did not respond to their registered letter. This has been documented in areas like military bases, where the citizens losing their right to vote are deployed oversees.
