Keep a Post-It-Note on the alarm. When you set it, you put the Post-It on the back of your hand or your nightgown, or whatever so it goes upstairs with you. When you want to know if you locked up yet, you look for the Post-It. In the morning, you stick it back on to the alarm box. :-)
No, that would get you disqualified as it would be considered trying to cheat. Enter only once a day under only one e-mail. If you are entering for another person, you can enter their name and email once a day also. But you can enter by postcard as often as you want.
I got in! I searched "housewarming gifts 2013" and clicked on the link for the "Thanks" page (the page you normally get to after you vote). That page asked me if I wanted to vote "again," and I clicked and it worked.
The "thumbs up" just means that someone enjoyed your post enough to take a second to click the icon. It's not so much a vote regarding the actual person, although people have developed friendships over the years. :-)
