Nova has always wanted to bring small YouTube channels to channels similiar to his. He later joined Together To The Top (or TTTT) (founded by AtheneWins on YouTube), an association where bigger YouTube channels give attention to smaller channels who probably deserve a bigger fanbase. Kootra then joined the group.
How it WorkedEdit
To get noticed by the two, you would've had to send the video you wanted to be noticed to ONE email to either Nova (email@example.com) or Kootra (firstname.lastname@example.org). Every week the two picked the best of the emails and put the videos in their YouTube banners.
