I've been partnered with them (officially) for about a week now. They have quick and good support. RPM only handles the contracts, that's it. Your dashboard will be the Maker Dashboard and CMS is through Maker. N4Gtv handles all the support and actual interaction with you. So far I have liked them. I haven't had anything amazing happen, but haven't had any complaints yet either. (other than RPM takes forever to handle the contract side of things)
He said he got accepted, not that he signed the contract. I actually applied to a few networks to see what my options were and where I would be accepted, before deciding on who to partner with. Except ATV I avoided applying there or anywhere that had a suspicious application process.
