Good luck with your networkCouldn't have said this better.... wow. But the thing is for small networks like mine that just started out, we have to et partners so get people to know who we are.
Hopefully you get big 

I would like to know more info on this too since mine is a gaming channel, still small but everyone starts off somewhere.
I'm intrigued.
RPM seems like a safe bet. If you work hard to get views and subscribers you can graduate to what could possibly be the greatest network for gamers; TGS.
VISO, I'm sure, is very similar to RPM but has no lock-in time.
For you, Crumble, I'd suggest RPM.
VISO messaged me aswell but I doubt it was anything special the message felt very copy and paste.
The recruiter that sent me a message was rather nice. Willing to offer a better contract then the one I currently have with RPM if I manage to leave them. But of course, I am not expecting anything "special". I've only got 860 subs with 20, 000 video views and have been doing this for one month.
However, I'm rather surprised that you got partnered. To avoid copyright you are required to do a commentary over the game-play footage. I wonder if they simply just overlooked it in your case.
Keep in mind that recruiters will pretty much reach out to anyone. Don't think that you need someone to reach out to you to get into a network. Look at others too.
