I was thinking about this one. My personal opinion is that you can be a supporter of the forums without having to donate money. Donating money is just MORE of a supporter. Not everyone can afford money to donate right away. Please feel free to share your opinions.
Well I, like many, support these forums by actively posting so as to avoid the possibility of a decadent ghost forum. While not specifically donating money, I donate my time - like others - by browsing through threads and posting as and when I get the urge.
