i have been with Freedom in 2015. and my butt still hurts. I have been looking and reading about MCN, and i found 95% of the things they can do or give. you can do alone, and many hot youtubers have droped and or never joined one.
so no need to jump head first, check around and see what you can do for yourself, cheaper and easier then the MCN states they could(and maybe cant)
