Donations
It doesn't cost very much to keep SabMagFaq on-line, but I'm too much of a Cheap Bastard to pass up any donations people may want to make. If I ever really need donations, I'll send a message to the SabMag email list.
HCoop
The wiki is hosted by HCoop. The basic dues, as of Dec 2009, are all of $7 per month, or $84 a year. You are required to maintain at least three-months worth of dues in your account at any time. You can have as much money in your account, waiting to pay the monthly dues, as you want. So, if you want to donate money to help pay the hosting fees, you can do so in a lump sum, and they will be used as needed.
Note: since your donation will go from PayPal straight to HCoop, I'll see the donation but not who sent it. So, let me say in advance: THANKS! The up side of this method is that I never touch the money, so I can't lose it. No, no, really--I have a bad habit of literally losing cash, checks, etc. Also on the up side, I can't use the money for anything but paying HCoop.
gandi.net
As of December 2009, it costs $17.94 per year to register the SabMagFaq.org domain name with gandi.net. There does not currently appear to be any way for other people to make payments into my gandi.net account to help cover renewal costs. Though, they've recently added PayPal to their billing options, so there may be something in the future.
