I've just put my money where my mouth is and donated $50 to Oxfam America to help care for those affected by the recent tsunami. My friend tas at LoadedMouth has set up a page for tracking blogger donations in his Blogger Tsunami Challenge and is pushing to spread the word by creating matching challenges. Here's mine:
The first person to let me know they've matched my $50 contribution can have the main character in my in progress novel named after them. If you ask nicely or exceed my contribution I could even give you a glimpse at my research/notes and let you shape the development of "your" character. Even if I don't complete the novel you can brag to all your friends that you "once were the main character in a novel". (People after the first are welcome to ask for secondary characters to be named after them...)
