Wow, thanks Gina for the compliments.

I bought a Flip camera and use that to make videos. I either prop it somewhere or have someone film me. Then I upload the video to my computer and use Windows Moviemaker to edit it. I'm not a whiz with technical stuff and I don't really have a lot of extra time, so I just do a basic edit and add my website and whatnot.
Once you create an account on Youtube, you can upload your video from there. The video cannot be any longer than 10 minutes, so make sure you edit it accordingly. I would also name your video as you'd like it to appear online before uploading it to Youtube, so you don't have to go in and change it after uploading it.
Hope this helps!
