This thread exists to explain to the anons browsing twentytwo on how to use the Japanese otaku video-sharing website Nico Nico Douga (Smile Video). So by the end of this I am hoping you will be able to upload videos, create mylists, and search for videos properly.
Nico Nico Douga's English variation platform was abolished recently although it wasn't really usable to begin with given how poorly it was maintained and nothing was explained to the user in the end.
I will also mention that the website best works with chromium based browser (I recommend ungoogled chromium, free of spyware) with Firefox there is tons of stuttering and slow loading times making it really unusable a lot of the times.
I will start off with Nico Nico Douga's Navigation Bar and explain what each of these tabs are.
