A "Causes" Application for Twitter, free online auction capability

By Abny Santicola

The site, launched in 2008 and recently redesigned, offers three main fundraising options: Nonprofits can set up online fundraising storefronts to sell new or donated items; they can host charity auctions; and individuals can set up personal donation pages in lieu of gifts for weddings, etc., that benefit the charities of their choices.

Charities can list up to 50 items in their storefronts at any one time for free. Stores can be upgraded to allow 100 items for a fee of $4.95 a month.
