Tip - YouTube auto-generated channels

[panzerboy]

I've been non-plussed that none of my Mandelbrot zoom videos were included in the auto-generated channel "YouTube - Mandelbrot Set".
I noticed the videos included were all of the category Science & Technology wheras I had been selecting Film & Animation as my category.
The tedious recategorisation sequence was video manager, edit, info and settings, category, Science & Technology, Save changes, back, (repeat).
Now I've successfully spammed the mandelbrot set channel with all my videos at once.
