So, I donated $5USD (what do you want, I'm not made of money) to PC and after I had done the verification @ PayPal, it took me to PPN Hosting. I said screw that and left (not knowing what I had done) ... Does this mean it wont come throught to PC and I've just lost $5 to Cyberspace?
Unless you confirm the transaction through Paypal, it won't get sent through, so I doubt that your money would have gone through. If you're worried about PPN Hosting, iirc that is Steve/Rukario's website or something, which is linked to the PokéCommunity. I would say it's just a way that it gets directly linked to him, instead of someone else.
I'm pretty sure that he has to log in, and then check for the update that you donated, and then go in and manually make you a Supporter. Given that, it can take awhile sometimes, but patience is good. xD If you're worried about it, then you could PM him, but he'll probably lurk this thread at some point.
