It looks like you are partnered with BBTV?
But to answer some of your questions:
Which one of the networks would you recommend for my gaming channel?
Fullscreen/Creator X (I'm in Creator X and LOVE IT!)
Are you happy at your network, if so, which one?
Yeah, I am pretty happy with where I am at
Would I be able to get into your network (include network name) with 400-500 subscribers and ~10k views?
As far as I know, Creator simple wants about 100 or views a day if I am not mistaken (that's where I was when I got partnered).
What is the support like at your network (Fullscreen/Creator X)
I think the Support Staff is great, I get quick responses, plus the Forum itself is pretty great!
What is the best way to apply to your network BESIDES directly through the website?
Either on there website, or be referred in.
If my channel grows enough, could you refer me to your network?
I don't see why not lol
Does your network pay a flat rate or a split percent? If percent, what percent do you receive?
Split Percentage, but I can't say my % though
Does your network usually pay you more or less then 2.50 CPM (Not asking for exact since you probably cannot say)?
I would say right around average for CPM, but I have seen some higher CPM's come through since the start of Tax Season.
