Did you remember your mama this year? If not you still have a few hours to send her something. Instead of wasting precious resourses on a paper card that by next week will probably end up on top of her refrigerator or under a pile of magazines, try an Ecards. They not only have Mother's Day greetings but you can find an Electronic Card for any occation. Birthdays, Anniversaries, Get Well, Congratulations, Christmas, Hanukkah, Kwanzaa - you name it. I even found a card for Chinese Valentine's Day!
Here are a list of some of the most popular ecard sites. Most have a big variety of free options but will require a membership if you want to send a more complicated card (ie: with your own music, photos or recorded greetings).
