An envelope from the City of Lowell was waiting in my mailbox today.  On the outside, it says

PLEASE OPEN IMMEDIATELY
RETURN BY MARCH 9, 2015

The enclosed form is pretty simple.  You just have to make corrections to the names, gender, date of birth and occupation of members of your household, sign and date it, and then return it to City Hall in the accompanying envelope.

The consequences of failing to reply are pretty dire from a civic participation perspective:

Failure to respond to this mailing shall result in removal from the active voting list and may result in removal from voter registration rolls.

So don’t delay.  Fill out the form and get it in the mail ASAP.
