How come the multipool isn't only for PC?

Do you own the pool or did you just ask them to implement PC for 3mil?
No, Coin King is a pretty popular multipool that can mine any coin (in their list) and give you the payout as PinkCoins. They will add your coin if they think the coin is going to have volume and deems profitable for them. That's how most of the multipools decide on whether to add any coin or not. In the early days, we never had any luck with the good ones, so we decided to pay a dev (a little over 3 mil) and have it in his lesser known multipool. Just a day after hiring him, we got information that Coin King was ready to put us on their site for free (I guess they saw the potential in the coin finally). So at the moment, the 1.5 mil collected (out of the projected 3 mil) is still under discussion. We might use it for further promoting pink, or use them to purchase votes on mintpal. We're still brainstorming on the best way to utilize the funds. I'm thinking a small portion of it for fayolong's lottery as well.
But first, I need to sleep

Tomorrow, I will make a small noob friendly screenshot tutorial on how to set up your payment as PC, etc on the multipool. This would be especially helpful for those with scrypt nscrypt rigs, as they too can mine with their rigs and earn PC.
Yeah, we were going to have it at a newer (albeit pretty good looking) Multipool, but we'd be sharing space with other coins there too, and we'd be paying 3m pinkcoins, plus guaranteeing the projected value of 3m pinkcoins with private funds, plus contributing to ongoing server costs. We gave the dev of that Multipool the go ahead to start work two days ago, and we were just going to cover the difference if we hadn't made up the full 3m pinkcoins.
You should note that we did make some contacts with some very professional people that could put together a big, custom multipool like some of the big coins have, but at this point the cost is several times what we could afford right now, but something we will consider in the future as we develop momentum!
It's not very clear from Sony's post, but the information about CoinKing came in just yesterday, and we've been working like demons to get things ready even earlier than predicted, because they wanted to add it immediately.
