(IPO updated with FriendFinder and All American Pipeline deal.)NEW YORK ( TheStreet) -- Convio is attempting to go public ... again. Convio, which provides software and other services that help nonprofit organizations raise money, said it expects to raise about $57.5 million in its initial public offering. Convio did not reveal its expected price range or the number of shares it is offering. The company previously filed for an IPO in 2007, but canceled the deal citing "market conditions." Convio's clients include the American Red Cross, American Cancer Society, World Wildlife Fund, People for the Ethical Treatment of Animals and Planned Parenthood Federation of America. FriendFinder, which operates adult entertainment and social networking Web sites, is also looking to raise $220 million in an IPO this week. The company expects to sell 20 million shares between $10 and $12 each. This would be one of the first social networking sites to go public, and could be a good indicator of how other companies like Facebook, Twitter or LinkedIn would fare.
