On Rattlebox you'll find video ecards for all sorts of things. There are, of course, ecards for things like holidays and birthdays. There are also ecards that are cute, that say congratulations, sorry and thanks, and their are ecards for many other sentiments. Then there are the adult themed cards. I didn't find a whole lot of them, but they're there. I don't recommend these for people under 18, or maybe 25.

Rattlebox's ecards are free and can be sent with just a few clicks of your mouse. If you want, you can customize them and add your own personalized messages to them. Add them to your blogs and social networking site too.

Just copy the code for the video ecard that you want to add to your website and paste it into the editing box on your site to add the video of your choice. Your site will need to have an editing box that supports code though. This won't work on Facebook but will work on MySpace.
