It's a good idea to help out Cody. This site runs upwards of $500+ a year to run, out of his pocket. It would be strictly optional. Maybe $5 a month. Package deals etc.. Nothing that you have the luxury of using would be taken away, but just enhanced. I'd be willing to install some new features on the forum as well to benefit those who wish to donate. It would be handled through PayPal via a vBulletin integrated donation system.
You guys just need to open your minds to new things and understand this community will always be free, even if we do take on something like this.
