After recording and saving the file, you just add the file as an attachment to an email. When the person gets your email, they can open the video with VLC, Windows Media, or whatever player they use.
I'm not sure if your computer has video recording software on it, but there is a great free, and easy to use program called Cam Studio. You can download it here. After shooting your video, there is another easy to use program for adding special effects and text. This program is called Many Cam.
Try it out. You can always shoot a video, add some special effects, and email it to yourself just for practice.
