Kristie and Ken Sigler are trying to raise money to complete the adoption of a boy from Guatemala with the help of the Web site realitycharity.com. The Siglers are hoping that strangers sympathetic to their cause will give them the final ,700 of the 6,000 they need for the adoption.

New York ? Ken and Kristie Sigler have sold cookbooks and football tickets to raise $16,000 for an adoption. For the final $8,700, they are appealing directly to strangers – through a new online clearinghouse that bypasses traditional charities.

Reality Charity LLC’s Web site, to be unveiled today, promises to be an eBay for fundraising. Those in need post appeals to pay off student loans, recover from a natural disaster or avoid a foreclosure. Those wishing to give respond to them directly.

The idea is to let donors choose their causes and beneficiaries and make sure their gifts aren’t diverted for overhead costs that most charities incur.

“We should cut out the middlemen and let the people decide,” said Alexander Blass, the site’s founder. “If I want to help sponsor your high-definition television, why not? But I may see your listing and I may reserve my sympathy for the Katrina victim or wounded veteran or adoption couple.”

The Siglers are hoping enough visitors will be moved by their financial plight to help them adopt a boy from Guatemala. The Hilliard, Ohio, couple say they are turning to the direct appeal after striking out with their church and traditional charities.

“There are a couple of places that provide grants for adoption, but they are few and far between and so many families are adopting,” said Kristie Sigler, who has raised about $200 of the $8,700 from seven donors during a private testing period on the site.

Using the Internet for direct appeals is hardly new. The practice, which skeptics have termed “cyberbegging,” gained momentum in 2002 after a 29-year-old New Yorker claimed that strangers sent enough money to her Web site to help pay off more than $20,000 in debt.

Scores of sites followed with pleas from single moms, recent college graduates with student loans and maxed-out credit cards, and childless couples seeking treatment for infertility.

Reality Charity wants to be a centralized place for such appeals – the “matchmaker,” in Blass’ words. Otherwise, he said, donors might not know of giving opportunities, and those in need might not know where to plead their case.

Donors from around the world can browse listings by type or location, search by keyword or click on a direct link passed along by a relative or friend. They can respond with a credit card or eBay Inc.’s PayPal payment service, with any transaction fees deducted and disclosed. Recipients must live in one of about 50 countries served by PayPal.

Contributions won’t be tax deductible because IRS rules prohibit earmarking of gifts to specific beneficiaries. Reality Charity is being run as a for-profit company, though it plans to make money from ads and groups that want to raise money – not from donors or individual recipients.

To give donors more confidence, would-be recipients who, for a small fee, submit to identity verification through credit-reporting agency Equifax Inc. will get a green check mark in their listings. Those in need also may post documents supporting their cause.

But ultimately, Blass said, the site will be self-policing. Similar to policies at eBay’s auction site or Craigslist’s classified listings, users will be the ones responsible for reporting suspicious appeals. Donors and recipients also will be allowed to withhold their full names.

Steve Jones, a professor at the University of Illinois at Chicago, questioned whether anyone ever received much through cyberbegging, short of a few cases that had garnered media attention.

“One of the things that compel some people to give money in some cases is the uniqueness of the situation,” he said. “If you’re confronted with many dozens of such cases on one site, I don’t know if people will find it as compelling to give to any one of those. It dilutes the impact of any individual story.”
