First, and the most important of all, Knowledge.
I've learned so much by joining Freedom!. When I first got started, I knew very little about being a YouTuber. I had no idea about Intros, Outros, Promotion, Copyright, etc. I learned all this by watching episodes of The George Show. And that was just at the beginning. As time went by, I learned more and more, and even today, am learning from The George Show.
Next, Music.
When I first got started, I was using music provided by Freedom!. Yeah, many people will argue that I could have got Copyright-Free Music from many other places for free. That's true, but since Freedom! was providing their own, I didn't feel the need to.
Next, Promotion.
This one was very recent. I got a shoutout on one of the episodes of The George Show. And yes, the shoutout did help.
Next, Socializing.
Joining the Freedom! Forums gives you a chance to socialize with other YouTubers, which is a huge plus point as socializing is very important.
Freedom! recently started providing free Graphics and Templates to the members. This isn't something that has helped me yet, because I don't use those graphics. I prefer to make my own. However, I'm pretty sure it has helped a lot of other members.
There are more ways that Freedom! has helped me, but this is all I can think of right now.
