Donating money not only can help PPN with the costs of keeping the forum up, you also get some really fun benefits added to your account if you donate money and obtain "Supporter" status a.k.a. those members with the green usernames.
There are 5 basic Supporter tiers and one hidden tier (which needs around $100 to get to) and the amount you donate determines which tier you get assigned to, and you can even donate more if you plan on upgrading your tier. There's a thread on donations where you can learn more about donation to PC and the Supporters.
PC is a bit laggy here and there, but that's just the server that's all. If PC's being too slow to load, I just do something else like go on Tumblr or even the Showdown server. Distraction is a good way to get around it, you never know when PC will start running smoothly again!
