MGN help my channel grow

MGN offers a variety of tools to help. An example is Tubebuddy and the free music available like Epidemic Sound and Position Music.
Besides that the new forum system wich you earn XP to level up and get exclusive perks.
Furthermore by networking on the Forums and finding those who share the same interest you can collaborate or make a party to grow together.
More features are coming in the near future so keep an eye out for the updates.

With this i hope your question is answered

 

MGN is the sub-network under Freedom and Tubebuddy has a detailed post on the main Freedom Forum forums explaining you get full acces as long as your partner.

Regarding the music you are right, the moment you unlink with the network you aren't allowed to use the music anymore.

For the promotion question MGN as well as Freedom offer help trough the community and tools to grow. Besides that there is the spotlight where members are given a shout out on the Freedom channel where people are chosen for random.

As for actual growth you have to work for the main part yourself as the network only provides support by means explained above.

If you have further questions feel free to ask

 

Networks like freedom and it's sub-networks (MGN) Don't promote you as in constantly tweet or make videos about you (unless you get lucky or win something.)They give you the tools to grow but it's up to you to use them.
