Hey Vivian.
Welcome! (though I'm practically new too, I haven't been here for months after I joined initially)
I do all things comedy as well, but I probably have quite a bit different - and older on average - audience.
I am working on animated stories - mostly captivating or fun short stories - including from
real people, which can be little anecdotes or sketches, which I animate.
So if you do want to collab sometimes, that type of video could be easily done from a distance
and work with both our content/audience.
I think your channel URL isn't working because you haven't chosen the right settings in your profile.
You might have a /user/ account and you'll have to pick that in your settings here on YTTalk.
