I discovered Take Them A Meal - an online resource for organizing meals for new moms, for the bereaved, and for the ill. Instead of making a bunch of phone calls or sending emails, everyone can go to the site, see who's bringing what and when, and sign up to participate.
In addition, they've launched Perfect Potluck, a similar site but for organizing potlucks.
If you've ever had to coordinate meals for such events, you must check this out! It's simple to use, has a sample schedule, and eliminates all those headaches and phone calls/emails!
