IPO Watch: Convio, FriendFinder - TheStreet

(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.

Meanwhile, a subsidary of

Plains All American Pipeline

(PAA) - Get Report

filed papers on Monday to raise $200 million in an IPO.

PAA Natural Gas Storage plans to use proceeds from the deal to pay off debt and for other corporate purposes.

Last week,

several companies came to market, pricing below expectations

.

Symetra Financial

(SYA)

, whose biggest investor is Warren Buffett's

Berkshire Hathaway

(BRK.B) - Get Report

, priced its stock at $12 each, the bottom of its expected range.

Chesapeake Lodging

(CHSP) - Get Report

saw only 7.5 million of its shares snatched up after offering 12.5 million and

Cellu Tissue

( CLU) priced 8.3 million shares at $13 each, below its expected range of $15 to $17.

Terrano Realty

also delayed its IPO until this week.
