"My tda" will be equal to those YouTube videos "My TDA Camp." For those who have YouTube account, works like this:
I say the theme of the week, you make the video, leave a message on my talk page stating that User has met the challenge and the name of YouTube User.
For those who do not have YouTube account, works like this:
Just make the image with the theme of the week and send the image on my talk page User.
The first theme is aliens. Good luck!
