Though BeachBoy beat me to it, I suppose I can put my two cents in. ;)
Being a PC Supporter is pretty great. Not just because you get quite a bit of perks, but because you're helping out PC! Though, if we are talking perks, the VIP Forum is pretty fun. All in all, I did it to help the PokéCommunity out. So, it's completely up to you whether you want to donate or not. It's not like anyone is going to make you...
