does it cost money to do this on youtube?

I am a little bit a lot upset, right now, and I figured I could take my mind off of what is going on by setting up my youtube account a bit better.

so, my question is, does it cost money to add channels to my other channels/featured channels box? does doing anything other than watching those full movies cost money? because I wanted to add some channels to my featured channel box, if I can figure out what exactly it is.

so, does it cost money?

btw, I have not posted any videos, yet, because my parents don't really want me to, yet. but feel free to subscribe, I know two people have already done so, because I post some pretty interesting comments. . . I get a little emotional, okay?
