It's absolutely NOT required to donate to this site... but if you have a few bucks to spare, it would be helpful in keeping the site running, since it takes money to run a website. Right now the expenses come out of the webmaster's not-so-full pocket.
(No, seriously, I have no job.) 

If you would like to donate, paypal makes it really easy. There's no specified amount, so you can choose how much or how little you want to donate. You can use most of the major credit cards or your paypal account, if you have one. 

We would love you forever and ever!
