help with 'community channels'

[George]

so my friend told me to try getting featured on a community channel and although he didn't mention much he sad it was a good way to get more know and make new friends on youtube. He didn't really explain how i would go about getting featured or even what a community channel is, could anyone help me out by explaining a little?

and I hope this is in the right section, i did search.

Cheers thanks guys!
