Help my friend and win valuable prizes

You may have noticed the widget that doesn't quite fit in my right sidebar.  It's for my friend, comic-book writer Jake Black, who's holding a fundraiser to help get out from under the mountain of debt due to his cancer treatment.

He's a third of the way to his goal, and to help a bit, I've offered a couple of prizes:

For a donation of $25 or more, you can get a signed and personalized copy of my story collection, Rejiggering the Thingamajig and Other Stories, which includes my Nebula-winning novelette "That Leviathan, Whom Thou Hast Made," plus 23 more stories. To claim this prize with your donation, be the first to put #anthology in the comment field when you donate. (Also include your name.)
For a donation of $50 or more, you can send me a short story (up to 7500 words) and I will read it and offer a detailed written critique.  To claim this prize with your donation, be the first to put #critique in the comment field when you donate. (Also include your name.)
